so either you are not linking to BLACS or your
BLACS is using different underscoring conventions.
you can easily find out by running 'nm' on your
BLACS library.

noooooooooo!

for the BLACS/SCALAPACK testers you have to keep the compiled
libraries
just where they are. apart from that LD_LIBRARY_PATH is consulted when
looking
for _shared_ libraries (dynamics shared objects to be more accurate,
since
it also applies to plugins that are dlopen()ed at runtime) at
_runtime_.
you have a linker error, so at best you can point LIBRARY_PATH to
where the
linker should look, but it would be even better to just use -L flags
or, if
you use the default setup for BLAS/SCALAPACK do nothing at all.

HTH,
