freebsd32 organization?

[Andrew Gallatin]

What's the "standard" way of installing 32-bit freebsd libraries
so as to be able to run a 32-bit binary?

What I did was to copy ld-elf.so.1 from a 4.9 machine to
/libexec/ld-elf-32.so.1, and then copy the 4.9 libs
to a lib32 directory, and then launch 32-bit binaries 
with a wrapper script that sets LD_LIBRARY_PATH to lib32.

This is a total hack,  and I assume there must be a better way.

FWIW, I'm doing this because firefox (built from ports cvsupped
today) exits randomly, so I'm running mozilla built on a 4.9 box..

Thanks,

Drew
