I deleted it. still seem to have the same problem. the signature for 
METIS_PartGraphKway  is different for petsc and libmesh  versions of
parmetis. 5.0.2 vs 3.1, respectively. would it be possible to put the two 
version in different namespaces ? 

Hmm... no namespace support for a C library.  The best route I can
think of here would be to add a --with-parmetis= rather than just a
--enable-parmetis configure option, so that users can switch to a
third-party library rather than the one in contrib/

btw what is the proper way to configure libmesh to 
undef LIBMESH_REQUIRE_SEPARATE_NAMESPACE  ?

The proper way is to write a new configure test for
--enable-namespace, send us a patch, then enable with
./configure --enable-namespace.  ;-)  We've been basically putting off
doing that ourselves until some user runs across a third party package
that really needs the separate namespace for compatibility reasons;
until then we just occasionally comment that bit out of libmesh_base.h
for testing.
