Talked to ouar OpenFOAM expert. He had the following comments:

* On a modern machine he compiled OpenFOAM-4.x in about 35 minutes.* gmp.h: Seems gmp-devel is lacking (probably also mpfr-devel.
* To speed up one could use "export WM_NCOMPPROCS=32" or something similar.
* Also, we have had serious issues with speed when compiling on parallel filsystem (gluster), should compile on a local filsystem.

> I'm building OpenFOAM 4.1 for a user, and it's been compiling the code for close to 3 weeks now. Yes, my build machine is a very slow old system (Dual-Core AMD Opteron(tm) Processor 1210, 1.8 GHz), but this still seems ridiculously long.
