Although MacOS X is listed on the site as one of the supported platforms.  It uses a non-posix call (GNU extension)
within the C library that does not exist on MacOS X: getgrent_r().  This call is in the file partition_mgr.c.
This is intended to be a reentrant (thread-safe) version of getgrent() that allows looping over the defined groups.  
Hence the code does not compile on MacOS X. 

The manpages for similar C functions are explicitly marked as being thread-safe.  However, this particular function
is not so marked and testing would have to be done to determine whether it is indeed thread-safe.  Rewriting the 
code would be fairly easy to do if getgrent() on MacOS X is indeed thread-safe. 

This problem occurs with both the production release of slurm (2.1.4) and the development release (2.2.0-0.pre2).
