Hi Luiz
While it's possible to use MPICH1 and PVFS2, it would be a good idea
for you to use MPICH2 if at all possible.
If you really need to use MPICH21, then I would suggest configuring
like this (you don't have to do it this way, but this is what worked
for me last time i built mpich1 with pvfs support):
prompt%: configure --with-romio=--with-file-system=pvfs+ufs+nfs+testfs+pvfs2 \
-cflags=-I${PVFS2_DIR}/include \
-lib="-L${PVFS2_DIR}/lib -lpvfs2 -lpthread"

You can look at config.log for more information about that error. It
looks like configre is not honoring your LDFLAGS environment variable.
Odd, since it is honoring your LIBS environment variable.
