That's less the problem than installing a later version of some module that
doesn't work with whatever Apple is doing with perl/python/ruby. I've had
the "joy" of this on Linux a couple times (notably, a Perl module version
required by my employer's tooling broke SuSE's X11 configuration tool), and
helped someone un**** their Debian system after they manually installed a
Perl module that broke dpkg.

At this point, the strong recommendation from *all* the upstream folks on
this is never touch the OS install except by OS tools; make a separate
installation if you want to install additional modules or different module
versions than are in the OS package manager. MacPorts adheres to this.
