For Debian Package:

The original SDPA tar.gz file includes 
MUMPS_4.8.4.tar.gz in this directory.
This file is contained for distributions
which do not have a MUMPS package.

Since Debian has its MUMPS package
http://packages.debian.org/sid/libmumps-dev
this directory does not contain 
MUMPS_4.8.4.tar.gz for Debian package.

If you need to compile from this source
package on the distributions which do not
have a MUMPS package, you should download
the original SDPA tar.gz from SDPA website.
