Brian: Thanks - I tried compiling 7.1.3a1 on osx and get this error:
gcc-3.3 -DHAVE_CONFIG_H -I. -I. -I../../share/include
-DLAM_TOTALVIEW_DLL=\"/sw/lammpi-xlf/lib/lam/liblam_totalview.so\"

As for openmpi, I get a lot of messages like this
global_ssi(1441) malloc: *** Deallocation of a pointer not malloced:
0xbffe9e70; This could be a double free(), or free() called with the
middle of an allocated block; Try setting environment variable
MallocHelp to see tools to help debug
global_ssi(1441) malloc: *** Deallocation of a pointer not malloced:
0x1; This could be a double free(), or free() called with the middle of
an allocated block; Try setting environment variable MallocHelp to see
tools to help debug
and then it crashes randomly with a seg fault (no error message).
