I've been running on FreeBSD amd64 in a jail(7.x-8.x), for quite a while without any noticable issues.
Are you using erde's autobuild scripts here? I'm assuming since you got it to compile you are at least using the freebsd patch included there.

You will need this additional patch as well:

+               fprintf(stderr, "[Error] Shared Library GetSym: '%s' failed.  Error=%s\n", name, load_error?load_error:"Null Return, no error");
+       }
        return(r);
 }

You will also need a line like this in your rc.conf file of the system hosting your jails:

jail_sysvipc_allow="YES"
