Leave the system Perl alone ( /usr/bin/perl ).  Especially the
redhat version, they messed it up to match their expectations.
Let rpm upgrades take care of any "improvements" added by
redhat to that, but otherwise keep the cotton-pickin hands off,
or Wierd Things Will Happen.

For everything else, install the Perl of your dreams in
/usr/local/bin/perl , and modify any scripts that are hardcoded
to /usr/bin/perl that you want to use it.  Since binaries in
/usr/local/bin are used in preference to /usr/bin , many scripts
will use the local version.

Besides keeping all the redhat perl scripts working, this also
leaves you with a version of perl on the system that may be bent
but is unlikely to get broken.
