Working on Debian FreeBSD, I have been putting BSD tools into /usr/bsd/bin, and
using PATH when I need them to build a package. The BSD kernel and libc want to
have the native make, rather than GNU make, so it seemed like an easy solution.
IIRC, Solaris has something similar in /usr/ucb/bin.

I'm having a larger problem with libraries. That's where most of the headaches
come from. Things like libnsl and libdl are in libc, but libintl is separate.
And some native Debian packages expect getopt to be in libc, instead of using
