I have made some simplifications here; fvwm95 was actually installed on an NFS server, but running against local shared libraries, so the /usr/local/bin hack was to simulate an a.out programinstalled without its dependent libraries. If you have an a.out FreeBSD box with some a.out packages installed, trying to run them via an NFS mount of that box from an ELF FreeBSD box should give the same results, since it did on about 10 machines here.
