I haven't never tried FreeBSD 7.0 so I don't even know if it is properly 
detected so that emulation code is used instead of native process-shared 
mutexes. Googling around, it seems that FreeBSD does not support 
process-shared mutexes, and the header unistd.h from FreeBSD:

http://www.freebsd.org/cgi/cvsweb.cgi/src/include/unistd.h?rev=1.80.2.1.2.1;content-type=text%2Fplain

seems to define _POSIX_THREAD_PROCESS_SHARED to -1, which is handled in 
boost/interprocess/detail/workaround.hpp to use emulation instead of 
pthread calls? Can you help me with this?

FreeBSD it's on my to-do list but I don't know when I'll have time to 
download, install and test it with Interprocess :-(

Please, try to get the latest SVN code for latest bugs and try to define

BOOST_INTERPROCESS_FORCE_GENERIC_EMULATION to avoid using pthread calls. 
But we must also see why FreeBSD configuration is not properly detected.
