You are likely running old binary built against FreeBSD 8.x.
The latter uses in-kernel implementation of semaphores.
FreeBSD 9.x switched to the new semaphore implementation based on umtx.
Here the kernel module is only used to support old binaries for pre-9.x.
So that's why you seem "Function not implemented" error message:
since in 9.x sem isn't present in the default GENERIC kernel.
I could try to kldload the module sem.ko, or better upgrade your system
canonically which means rebuilding nginx, as said in another mail.
See http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
for the canonical way to update your system.
