I think the consensus on the list was to use bundles. If you are not
convinced yet, then have a look at this:

osx$ file /System/Library/Perl/darwin/auto/Socket/Socket.bundle 
/System/Library/Perl/darwin/auto/Socket/Socket.bundle: Mach-O filetype=8 powerPC

osx$ file /usr/lib/python*/lib-dynload/_socket.so
/usr/lib/python2.2/lib-dynload/_socket.so: Mach-O filetype=8 powerPC

(FYI: filetype=8 are bundles)

Ok, this is a reasonable request. I'll try to rewrite the loadlib patch
to use the _dyld_* functions instead.

But there needs to be a definitive decision regarding bundles vs. dylibs
first.
