They don't.  They merely take shortcuts to get a good approximation.  Here
is what happens: Perl uses MakeMaker to create the Makefile.  But under
Unix, make does that actual work of deciding what _really_ should be done.
Under MacPerl, we just take that data that would be used to construct a
Makefile (and the Makefile is actually created but not used) and install
what we think should be installed.  It ends up being possibly different
from what make would do (of course, this is true of varying platforms and
versions of make).

Only because I basically have it install anything in :blib:, and the binary
distributions already have the binaries in the right spot for installation.

If you can tell me how to know this for sure, then I could perhaps include
it.  But I don't know if that can be done reliably.

Sure, but as we discussed, that might not mean that a compilation is
actually required for the module to be installed and work properly.
