OK.  The way it stands now, the perl5 pkg will attempt to use ELF dlopen()
semantics if /usr/libexec/ld.elf_so exists, and will use the "old style"
modules (ld(1) a temporary interpreter, and statically link everything) if

If this looks OK to the mips folks, I'll forward a patch back to the Perl
team for integration into the Perl mainline source.
