OK. I have made some changes in the source that lets me build on AIX 5.2. I thought I could post the patch here and perhaps someone can tell me if I am on the wrong track or if this is an OK fix on AIX. Basically I have changed setup.py to define HAVE_SEM_TIMED_WAIT=0 on aix. I have also defined CMESG_SPACE and CMESG_LEN in terms of _CMSG_ALIGN (see http://homepage.mac.com/cjgibbons/rubyonaixhowto/x72.html) in multipocessing.c. (I realise that this breaks some other platforms, but right now I just need to build on AIX).
