Mathematica 6.0 on FreeBSD 7 Anybody?

Greetings,

Anybody get MMA 6.0 to run under FreeBSD 7?

The FreeBSD handbook worked great for Mathematica 5.1 when I was running
FreeBSD 6.3 but I haven't been able to get it to install under 6.3 or 7.
I've modified the scripts to run "#!/compat/linux/bin/sh" & "sysctl
kern.fallback_elf_brand=3" The kernel modules linux & linproc are
loaded and linprocfs mounted.

When I run the installer, I get to the greeting and then it hangs until
I break out. An error message is printed:

ls: error while loading shared libraries: /usr/lib/librt.so.1: ELF file
OS ABI invalid
SIGINT

I have the following:

/usr/lib/librt.so.1 branded FreeBSD
/compat/linux/lib/librt.so.1 branded SVR4

Even if I temporarily rebrand the librt from SVR4 to Linux, I still
can't get MMA 6.0 to install.

Any help appreciated,

Monty
