gprolog on Mac OS X (Darwin 1.3.1)?

[spratt]

I'm interested in a port of gprolog to Mac OS X (Darwin 1.3.1). Has 
anybody already done this?

I've gotten it to the point where all of the .c compiles and two of the 
.wam compile (foreign.wam and pl_error.wam). I'm currently stuck with 
utility.wam getting an error from 'as' with Load_Cut_Level being an 
undefined label.

Thanks.
