 I&#39;ve built openmpi version 1.3.3 on a MacPro with OS X 10.5.8 and the Intel 10.1.006 Fortran compiler and gcc 4.0.  As far as I can tell, the configure and make commands completed fine. There are some warnings, but it&#39;s not clear to me that they are critical - or the explanation for what&#39;s not working. After installing, I try to compile a simple F77 hello world code.
