Again, other distros have would have this problem if I ported them to
FreeMiNT. So many things these days want shared libraries, but I don't
have that luxury at this time.

I'm o.k. to go with this flow, but I'll need some assistance on what the
best route to package.mask'ing of sys-devel/libperl is, and then I've
got to get dev-lang/perl to generate the static lib.

Because the .a is already created as a static lib, so no link is
required as shared libs aren't supported.

Just something to remember on this, is that I do have the entire
Gentoo/Prefix bootstrapped on FreeMiNT already, so supporting this
configuration is not impossible. I just need to work through the patches
I have with the guys here to resolve issues like this the best way for
everyone.

Thanks to all for the input I've received.
