- Take a look on the output of the compilers (make >&make.log; less 
make.log). Probably there's a problem with some files in mpid/ch_p4(/p4) 
to compile correctly. Knowing the actual problem makes it easier to fix.

- Why do you need mpich-1.2.6 - it's mostly a bugfix release of 1.2.5. 
Do you see any bugs with 1.2.5?

- What about MPICH2? Performs significantly better with socket 
communication.
