"Function not implemented" is a fairly serious problem. Essentially,
the operating system does not have IPC support. FreeBSD does have it,
so I suspect this could be caused by your running it in a jail setup.

Indeed, Google turned up this description of restrictions for processes 
running inside FreeBSD jails: 

http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/jail-restrictions.html

This very clearly shows that support for IPC using shared memory and 
semaphores is not supported for jailed processes. There is a 
"jail_sysvipc_allowed" sysctl setting (defaults to 0 - "off") that
might enable IPC support inside the jail; I couldn't quite tell from
this webpage.
