   Can someone walk me through what I need to do to build 64-bit
   binaries on Snow Leopard?  I saw the thread on how to build LIAR
   64-bit, but what about the rest of it?  I currently have the latest
   (January) 32-bit binaries installed.  I'd like to build from the
   latest git sources.

It is easiest to start by building the portable C distribution from
the 20090107 snapshot, per the instructions on the web site at
<http://www.gnu.org/software/mit-scheme/liarc-build.html>, but you may
need to force that to be a 64-bit executable on Mac OS X, so rather
than executing

sh etc/make-liarc.sh

you need to execute

CFLAGS="-arch x86_64" LDFLAGS="-arch x86_64" sh etc/make-liarc.sh

Once you have installed the portable C distribution, you can fetch
Scheme from Git and run, from the src directory in the Git repository,

sh etc/make-native.sh

Then you can install that Scheme with `make install'.

Be aware that the native x86-64 port is still a work in progress;
don't hesitate to report problems with it.
