Great ! :D

Done.

Spec URL: http://sagitter.fedorapeople.org/MUMPS/MUMPS.spec
SRPM URL: http://sagitter.fedorapeople.org/MUMPS/MUMPS-4.10.0-3.fc18.src.rpm

Well, this is what's reported in README file:

Sequential version
------------------
You can use the parallel MPI version of MUMPS on a single
processor. If you only plan to use MUMPS on a uniprocessor
machine, and do not want to install parallel libraries
such as MPI, ScaLAPACK, etc... then it might be more convenient
to use one of the Makefile.<ARCH>.SEQ to build a sequential
version of MUMPS instead of a parallel one.

It seems me that can be used the only parallel version. Hold the sequential one
can be an option.
