[SOLVED] dlopen failure on sbcl/macosx

I found the reason for my problem: My SBCL is built for 64 bits, but
cc builds for 32 bits on this machine unless I specify -arch x86_64 on
the command line.

The change below fixed the problem for me. Of course, I would need a
similar fix for any dynamic library I wish to load; but that will be a
battle for another day. At least, I now know wherein the problem lay.

(This is of course not the correct fix in general, since it will break
on 32 bit lisps. I am not sure how to deal with that little problem.)
