We're trying to avoid requiring anything that's not in a "standard"
Perl installation, with the exception of course of IPC::Run which
there's no way to avoid using.  Now, the "standard" set is a bit
fuzzy, but certainly if a module is not present in some major
distro's minimum Perl package set then using it is a problem.
