This looks like some header file in your system defining a macro called 
"barrier" that interferes with a function of the same name in MMTK. 
It's not on Python, Numeric, or ScientificPython (as I have the same 
versions of all those), so it must be headers coming with gcc or with 
some other library such as libc. What brand of Linux are you using?

Assuming that my guess is right, the easiest fix is to add the line

	#undef barrier

at the beginning of the file Include/MMTK/forcefield_private.h

However, I would still be interested in tracking down the origin of 
this error message, as others are likely to experience it as well one 
day.
