Gentoo: Installing perl modules using CPAN

After seeing this interesting example - http://secviz.org/?q=node/74, I feel like trying out afterglow with argus on my gentoo laptop. I install graphviz with emerge and download afterglow instantly.

shell>wget \ http://optusnet.dl.sourceforge.net/sourceforge/afterglow/afterglow-1.5.7.tar.gz

shell>tar xvzf afterglow-1.5.7.tar.gz

I try to run afterglow and I get an error -

Can't locate Text/CSV.pm in @INC (@INC contains: /etc/perl /usr/lib/perl5/vendor_perl/5.8.8/i686-linux /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib/perl5/site_perl/5.8.8/i686-linux /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib/perl5/5.8.8/i686-linux /usr/lib/perl5/5.8.8 /usr/local/lib/site_perl .) at /home/geek00l/i-Apps/afterglow/src/perl/graph/afterglow.pl line 111.
BEGIN failed--compilation aborted at /home/geek00l/i-Apps/afterglow/src/perl/graph/afterglow.pl line 111.

Since CSV.pm is not ported to gentoo portage, I have to use cpan instead -

shell>export LANG=en_US shell>perl -MCPAN -e shell

Your configuration suggests that CPAN.pm should use a working
directory of
/home/geek00l/.cpan
Unfortunately we could not create the lock file
/home/geek00l/.cpan/.lock
due to permission problems.

Please make sure that the configuration variable
$CPAN::Config->{cpan_home}
points to a directory where you can write a .lock file. You can set
this variable in either
/usr/lib/perl5/5.8.8/CPAN/Config.pm
or
/home/geek00l/.cpan/CPAN/MyConfig.pm

Could not open >/home/geek00l/.cpan/.lock: Permission denied

Permission problem, easily solved with sudo -

shell>sudo perl -MCPAN -e shell

There's a new CPAN.pm version (v1.9102) available!
[Current version is v1.7602]
You might want to try
install Bundle::CPAN
reload cpan
without quitting the current session. It should be a seamless upgrade
while we are running...

cpan>quit
Lockfile removed.

Now I can use afterglow without much problems. It is decent tool to create network graph if you ask me, my friend mel has done it here with interesting example.

Peace ;]
