I tried installing ibmonitor using the ibmonitor-1.4-1.noarch.rpm RPM file I obtained from ftp://download.fedora.redhat.com/pub/fedora/linux/extras/6/i386. However, when I tried to install it, I got a message indicating the Term::Readkey module was missing.
# rpm --install ibmonitor-1.4-1.noarch.rpm
warning: ibmonitor-1.4-1.noarch.rpm: V3 DSA signature: NOKEY, key ID 1ac70ce6
error: Failed dependencies:
perl(Term::ReadKey) is needed by ibmonitor-1.4-1
# perldoc -l Term::ReadKey
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Term/ReadKey.pm
But when I used the perldoc -l command to check on whether all
of the required modules for ibmonitor were present, I saw it listed.
$ perldoc -l Term::ANSIColor
/usr/lib/perl5/5.8.0/Term/ANSIColor.pm
$ perldoc -l Term::ReadKey
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Term/ReadKey.pm
$ perldoc -l Time::HiRes
/usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi/Time/HiRes.pmI also saw it listed when I used the find-modules.pl script I have on the system.
# ./find-modules.pl | grep -i ReadKey
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Term/ReadKey.pm
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Term/ReadKey.pm
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Term/ReadKey.pmWhen I used the one-line Perl command perl -MTerm::ReadKey -el
Perl did not complain. Nor did it complain when I tried perl -e
'use Term::ReadKey;'. If the module wasn't found by Perl it should
complain it couldn't locate the module anywhere when I used either command.
And when I used the List Perl Modules CGI script, I have on the system, I also saw it listed there. So I didn't know why I got the message indicating the module is missing when I tried to install ibmonitor.
I used the locate command to look for any other occurrences
of the file ReadKey.pm on the system, which showed the following.
# locate ReadKey.pm
/root/.cpan/build/TermReadKey-2.21/ReadKey.pm
/root/.cpan/build/TermReadKey-2.21/blib/lib/Term/ReadKey.pm
/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Term/ReadKey.pmI decided to try downloading and installing the module again through CPAN.

Lockfile removed. Installing the later version of ReadKey.pm didn't help, though. I still got the same error message when I tried to install ibmonitor.
# rpm --install ibmonitor-1.4-1.noarch.rpm
warning: ibmonitor-1.4-1.noarch.rpm: V3 DSA signature: NOKEY, key ID 1ac70ce6
error: Failed dependencies:
perl(Term::ReadKey) is needed by ibmonitor-1.4-1
I downloaded the src.rpm file,
ibmonitor-1.4-1.src.rpm
. Installed it with rpm --install ibmonitor-1.4-1.src.rpm, which created two
files: usr/src/redhat/SOURCES/ibmonitor-1.4.tar.gz and
/usr/src/redhat/SPECS/ibmonitor.spec. When I checked the ibmonitor.spec file,
I found the following line in the spec file:
Requires: perl(Term::ReadKey)The Term::ReadKey module is only needed for ibmonitor fo changing the display on the fly by hitting certain keys, e.g. "m" to show the maximum bandwidth used while the program has been running. The program, which is a Perl script, will run without ReadKey support being present on the system. There is code within the script that checks for the presence of the module, but doesn't require it to be present. That code is shown below.
# Check for installation of Term-ReadKey module
eval q/use Term::ReadKey;/;
if (!$@) {
$useReadKey = 1;
}
Since the module is actually present on the system and I can change the ibmonitor display by hitting
the keys that trigger options in the program, such as the display of maximum bandwidth, I used
rpm --nodeps --install ibmonitor-1.4-1.noarch.rpm to ignore the dependency check
for Term::ReadKey and proceed with the installation of the ibmonitor
RPM file. The program worked fine after
the installation.
The RPM installation installs the following files:
$ ls -l /usr/share/doc/ibmonitor-1.4/
