I think it is pretty hard to draw a line between code and custom 
configuration and what you have to do to keep them working as other 
things change.  For example I once ran smail with some custom tweaks to 
work with binary attachments from a proprietary (AT&T) PC mail program 
and uucp. And some glue between that, hylafax, and a custom print 
spooler.  They were, ummm, non-trivial to keep working over a period of 
several years, especially when smail sort of disappeared.  But that was 
back before there were packaged versions of much of anything and you 
couldn't even count on updates to compile.  The code that I controlled 
directly wasn't quite the same kind of problem.

If you have different users needing these things on the same machine you 
must at least have run into situations where someone needs one version 
of a CPAN module or a new php/python/mysql version when at the same time 
someone else is running something that won't work with it.

You might have run into the CPAN issue if you installed something like 
RT in the Centos 4 era.
