Need to update PERL

[Sysadmin]

I'm in a bit of a quandary.  I need to update my Perl 5.8.0 to Perl
5.8.3.  

The problem is...it was installed in RPM form when the system was
built.  Checking the the installed RPM's shows now les than 2 dozen
RPM's that appear to be addons to Perl.  To make things worse, I am
unable to find an RPM install of Perl 5.8.3.  I have no problem with
compiling source but
1) I'm not sure about how "install/upgrade" over the current
2) worry about that "breaking" some or all of the addons.

Suggestions, options, cautions appreciated
