Getting guile-1.6.4 to work on OS/X

It took me several tries to get guile-1.6.4 to build and install
correctly under OS/X.  Here's what I did:

1. Installed the `dlcompat' package from fink.  (I think this may just
   be part of the stock fink install, actually.)

2. Got a tarball.  Make `distclean' because (at least in my tarball)
   whoever packaged it forgot to.

3. Applied this patch:

   I found the first chunk on the web somewhere.  I can't remember
   exactly what it fixes.  The second patch fixes the fact that OS/X
   doesn't have an `environ' when you link into a dylib.  Stole it
   from Tcl, IIRC.

4. Configured with:

     CFLAGS=-I/sw/include LDFLAGS=-L/sw/lib \
     CPPFLAGS="-I/sw/include -traditional-cpp" ./configure

   You need to pick up the stuff in /sw/* (namely, dlcompat) for guile
   to realize that it can do dynamic linking.  Specifying
   `-traditional-cpp' avoids some brain damage with the pre-compiled
   headers that otherwise cause the build to take *hours*.

5. Run with DYLD_LIBRARY_PATH=/usr/local/lib, otherwise dyld won't
   find any of the stuff that's `dynamic-link'-ed (e.g., srfi-13).
   Anyone know how to add this to OS/X's default install path?  I.e.,
   the equivalent of /etc/ld.config on Linux?  I suppose I could just
   re-build and have it install stuff in /usr/lib, but...

Anyway, good luck.  Comments or feedback welcome!
