For "plug-and-play" usage, MS much prefers that the machine has just one
perl installation which has been cleanly installed and maintained.  It is
possible to run on machines with two (or more?) perl installations that
are each clean (and I've done so), but it perhaps won't "plug-and-play".
If you then start diddling and moving around bits of perl, its libraries
and its modules, that is almost certainly asking for trouble.

(As perl modules build, they often know, and need to know, where they (and
each other are); moving them confuses them mightily.)

Consider cleaning out all remanants of all perls and, after checking that
all traces of all perls really have gone, then re-install a single perl of
your choice into a single location of your choice ("/usr" probably
preferred to "/usr/local") and maintain it cleanly there.

Then, and only then, return to MS, which should then cleanly install.

Sorry if that sounds a bit harsh!  (Much in life is multitudinous and
subtle shades of grey.  But MS's preferences for a single, clean perl is a
more blatant black and white issue.)

Hope that helps.
