gmake can also thread using the -j option. Most open source distributions of software will build properly in parallel using either gmake or dmake, but there are a handful I've run into that sometimes have trouble with it, probably due to incompletely declared dependencies in the Makefile or something. I seem to remember that a few years ago, a T2 was once cited as being able to build the Solaris kernel faster than an 8 core AMD. We currently have an M4000 (8 cores SPARC64-VI 2.1 GHz, 2 threads per core) that we do our compiles on, and that's been able to compile almost as fast as the identical software on an 8 core Intel X5460.
