Try repeating the Perl build with shared-lib selected and then just
installing the resulting libperl.so beside libperl.a. However:

That advice is doubtless platform-specific, and I think it may well be
horsepucky for Intel-based Linux. Isn't *all* code built
position-independent on that platform?

I believe you could actually use a non-shared libperl.a on Intel Linux;
just dike out the test for shared-ness in plperl's Makefile.PL.
The reason it's there is we couldn't think of a direct test for
position-independent code, which is the real requirement...
