[rt-users] Dependencies for RT 4.0.5 on CentOS 5

[Stephen J Alexander]

the pair of quotes are necessary after the -e (null argument - but it needs
an argument in any case). If there's an error it'll exit without the -e "",
 but without an error it'll just sit there waiting for you. The -e is not
important in the grand scheme of things.

to remove the symlink, just "rm /usr/bin/perl" -- but note that CentOS
might want there to be a perl there (i'm not sure about dependencies in
that OS), so you may just as well "mv /usr/bin/perl58 /usr/bin/perl" to
undo what you'd done earlier.

To build cpan is a bit involved and somewhat off topic here so I'll refer
you to the documentation on http://www.cpan.org, but you may not need to
build it... check first to see if it came with your perl installation by
attempting to run "/usr/local/bin/cpan" - if this works, then you're off
the hook. Just make sure to run cpan and perl with the fully-qualified path
instead of just the command name.

Also, when it comes time to install RT, I think you will have to specify
that perl is located at /usr/local/bin/perl instead of /usr/bin/perl
