[gmx-developers] Problems building for OS X with threads

Hi, all-

I'm very recently (with 4.6 updates in the last couple of weeks) having
issues with building gromacs with threads on OS X.  When I try to compile
with shared libraries, I get:

ld: warning: in /usr/local/lib/libgomp.dylib, file was built for i386 which
is not the architecture being linked (x86_64)

When I build without shared libraries, it compiles, but crashes when run
with -nt more than 1.

Currently using OS X 10.6.8, gcc 4.1.2 to compile.

Everything works fine with 4.5.5, and with earlier versions of 4.6.

Anyone else having similar problems, or know what changes could have caused
