Cool! Good to hear that.

Hmm.. Quite frankly, I am puzzled.
The only thing I can think of is the following:
Why isn't there a "-L /opt/pvfs2/lib" on the gcc command line? It is
perhaps not picking up your LDFLAGS and therefore not able to locate
libpvfs2.a. Also, can you double check to see if libpvfs2.a is indeed
installed in that path?
Other than those guesses, I do not know why the build failed..
Is that all
config.log/config.status had? If the file is not too big, can you just
mail those to me off-list?
