Good point. And actually, until recently, I wouldn't have known a better
answer than "hmm, that's indeed a weak spot". However, recently I learned
about "local::lib" which allows one to install Perl libraries to a
specifically named directory. It can be used with CPAN, which means that
upon installing LedgerSMB, you'd be able to install its dependencies to the
same directory (if you want).
The way it's done is that the content of that directory overlays the
content of the system-provided libraries, allowing for different versions
of a module to be installed for "main Perl" and "local::lib" 'instances'.
Although 'local::lib' isn't anywhere in our documentation currently, I
think that Perl should be able to handle the concern you raise through the
creation of multiple local::lib directories. So, today, I'm answering your
point with "yes, it can" -- noting that we need this to be documentated
somewhere.
