Yes, I have it running on my Nehalem Mac Pro. As I indicated, I used MacPorts 
to build universal binaries (ie, i386 and x86_64) of all the dependencies. I 
also built libcanberra, but in the end did not use it.

I then downloaded the latest snapshot. I changed libtoolize to glibtoolize in 
autogen.sh. I did not modify configure.in. I configured with --enable-threads 
CFLAGS=-arch i386 LDFLAGS=-arch i386 and then did make and sudo make install.

This built a  32-bit binary --- gnubg: Mach-O executable i386. Sound works fine 
using the QuickTime framework.

Haven't done much, but things seem pretty good. There is a problem with Full 
Screen mode, especially for 3d-board, but it seems to be related to Snow 
Leopard based on the Googling I did. One positive---multithreading is now 
working as it should for me. With hyper-threading I have 16 logical cores, and 
when I set Eval Threads to 16 and rolled out a position, my CPU usage was 1600% 
(on Leopard it would never go above 200%). (It seems that multithreading not 
used during basic gameplay---is that correct?)

Don't know about the accuracy of the built-in speed estimate, but I got 
158056064 static/evaluations/second.
