Honestly, there's no benefit to replacing the vendor's perl, and huge risk.

If you compile your perl in some custom location (/usr/local or 
/opt/perl), and make sure it knows to respond to '#!/usr/bin/perl' on 
the shebang line (it's a configuration option when compiling perl, the 
shebang line doesn't have to match the path), then all you have to do is 
change your PATH environment variable so /usr/local/bin (or 
/opt/perl/5.8.8/bin) comes before /usr/bin, and you'll always get your 
compiled perl instead of the vendor's perl, while the rest of the system 
will get the vendor's perl.
