I would _definitely_ recommend using the sgi compiler instead - gcc will 
be much, much slower.

Are you sure you don't have the sgi compilers? You might have to install 
them from a CD or something.

If you want to compile using gcc on an sgi, you might have to specify 
the compiler flags explicitly, and you should probably disable fortran 
loops even if you have g77 installed (g77 can be slower than C code).
