Perhaps on your old system it was just part of your standard libraries. I kind of
fuzzy on how all this works, but I belive the compiler should have some sort of
setup that tells it where to look for core libraries, and on some systems crypt
would be part of that default, but on other it would not. Also, I am pretty sure
you can automate some that stuff with "make", and if you used a different make
file, or because it was a different platform, perhaps the makefile was not setup
proprely.Anyway, I think it boils down to some sort of a configuration
issue...james

P.S. Any more definitave answers?
