When trying to run an opensim server on FreeBSD I get the following error
report:

Stacktrace:

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Abort (core dumped)

I have tried with both the binary package (pkg install mono) as well as the
port (cd /usr/ports/lang/mono && make install).

The FreeBSD version is:

FreeBSD sim 8.4-RELEASE-p14 FreeBSD 8.4-RELEASE-p14 #0: Tue Jul  8 12:41:46 UTC
2014     root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

And mono is running inside a jail.

mono --version reports:
