[mpich-discuss] Problems with running make

[Ron Palmer]

I am running centos on two of these, sargeant and constable, and RHEL on 
the third, gainsborough.

By runtime libraries, do you mean for the three compilers included, ie 
gcc, fortran77 and fortran90? Please use one syllable words, I am the 
edge of my understanding :-(.

Thanks
Ron
