Okay I got it to compile with "LIBRARIES = -lm -lcrypt". Seems to work
fine except for the things regarding crypt. Got the following
recommendations from someone from the MOO list.

Do the following from inside the MOO environment in question:
;crypt("some string")
you should get back something along the lines of (this is an example, yours
probably won't be the same string. Doesn't really matter what you get back):
=> "wOCq7A/q9eOLk"
Now take the first two characters from that response, and run crypt() again
with them as the second arg:
;crypt("some string", "wO")
You should get back the same result:
=> "wOCq7A/q9eOLk"
If you don't get back the same result as the first crypt() call, your unix
crypt implementation is broken, and that's your problem. I don't know much
about FreeBSD, but if you can't figure out how to get its crypt function to
work right, you could try getting the GNU crypt implementation (the GNU Ultra
Fast Crypt library, available from many (particularly non-US) GNU FTP sites)
and try having the MOO use its crypt function instead of the FreeBSD one..

As you can guess, it doesn't work. Doe FreeBSD use the GNU crypt?
Thanks folks,
