EDIT: This may already be out of date. This was for version 5.2.2.22-3. As of 5.2.3-1, these steps were not necessary for me.

-------

To install this package, I needed to follow the steps here (copied below):

https://gforge.inria.fr/forum/forum.php?thread_id=33981&forum_id=598&group_id=186

Inside the src repository :
- cp config/LINUX-GNU.in ./config.in
(any configuration file can be used and not need to be modified)
- make murge_up
- make sopalin/src/murge_fortran.c

Once I had completed these steps, I was able to run makepkg and install the package.

There is inconsistency between scotch and pastix integer types. Scotch integer type is 32bit integers and pastix uses 64bit. This results in the following runtime errorr:

ERROR: Inconsistent integer type

The following change to pastix config.in solves the problem:
