Right.

Solaris does have sem_open:

http://docs.sun.com/app/docs/doc/819-2243/sem-open-3c?a=view

However, I suspect the issue is that blastwave's packages (typically) 
are compiled on Solaris 8 or Solaris 9, instead of Solaris 10 or 
OpenSolaris 200x.

Going farther, I see several bugs related to enabling _multiprocessing 
on Solaris on the python bug tracker.  Here's one of them:
