I just upgraded to OSX 10.5.2 on my imac
and am trying to install openmpi  for use with absoft fortran 90
based on their instruction page:
http://www.absoft.com/Products/Compilers/Fortran/Linux/fortran95/BuildingOpenMPI_MacIntel_v101.pdf

I got into trouble as per info below.
Seems to be a gcc problem.

any suggestions?
Thanks for helping.
Frank
