[mpich-discuss] undefined symbol: MPI_UNWEIGHTED

[Robert Baurle]

Sorry, I should have also stated that /opt/mpich is a symbolic link to 
/opt/mpich_gfc. I define /opt/mpich to be a symbolic link to either:

/opt/mpich_gfc

or

/opt/mpich_lahey

depending on which Fortran90 compiler I want to use. I currently have 
/opt/mpich symbolically linked to /opt/mpich_gfc, and /opt/mpich is 
defined in my paths as shown below

hyp22 rbaurle > echo $LD_LIBRARY_PATH
/usr/lib64/atlas:/opt/tecplotex/bin:/opt/mpich/lib:/opt/lahey-64/lib64:/usr/local/lib

hyp22 rbaurle > echo $PATH
/home/rbaurle/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/sbin:/opt/lahey-64/bin:/opt/tecplot/bin:/opt/gridpro/bin:/opt/mpich/bin:.:/home/rbaurle/Vulcan/vulcan.bzr/Vulcan/Scripts
