Why would someone run something new like Subversion, and not bother to upgrade their ancient Perl? Upgrading parts of your system while other parts are left to rot in legacy mode just seems like trouble.

Thus spake someone who hasn't had to maintain systems for the long term. :-)

Many times it is necessary that particular versions of perl, modules, libraries, etc. are all required just to make the mission-critical application work. "Upgrading" is often counter productive and costly (due to time lost chasing down weird interactions and fixing them among other things).

Switching from CVS to SVN (for instance) is something that is likely to only affect the development team while switching from perl 5.005_04 to 5.8.6 may affect everybody.
