Linwei,
Have you tried using -funderscoring with gfortran. I don't think the
trouble you are having is caused by having g77 and gfortran both
installed.
Do you know where the unreferenced symbols (_s_wsle, _e_wsle, etc )
are supposed to be coming from. If they are in your fortran programs
then using -funderscoring should help.

Dear Reeder,
I've tried add gfortran flag "-fno-underscoring", but the same
errors persist...
Is that possible because that I have both g77 and gfortran in my
computer?
Best,

Linwei,
Is there a problem with trailing underscores. Are you linking c/c++
files with fortran. Do the _s_wsle family members need to have a
trailing underscore
where are the unrefernced symbols supposed to be coming from. If they
have a trailing underscore in their names you probably need to add a
command line flag to you fortran command to append the underscore.

Dear Dr. Simon,
Do I need to remove g77 from my computer then? Since after
installing
gfortran (for Leopard), there is some link problem with gfortran..
When I try to build some routines in the BLACS, it gives error like:

for some which is successfully built, it can not be run either,
giving
errors like:

mpirun noticed that job rank 0 with PID 14541 on node iris-

The second problem happens when I use g77 too, but there were no
linking problems with g77...
Thanks for any help!
