Comment (by sean@…):

 Replying to [comment:8 wimmer@…]:
 > Now, it is worth noting that the parmetis switch does not include all of
 the functionality of the metis switch, as MUMPS offers more functionality
 when only sequential analysis is used (see documentation of the ICNTL(28)
 parameter). Hence, one would like to include both parmetis and metis at
 the same time anyways (I noticed that your Portfile only had parmetis
 included). If a user would want to use the sequential version, there is
 not reason for him to use the parallel analysis at all (it gives no
 additional functionality, but even reduces it), but he/she would always
 need to link against parmetis/ptscotch.

 parallel versions.

 > That in addition to the fact that while I believe that it is probably
 possible to use the parallel version in sequential mode without mpi (by
 linking against mpiseq and dealing with different mpi's properly), the
 MUMPS web page does advocate separate sequential and parallel versions
 (http://graal.ens-lyon.fr/MUMPS/index.php?page=faq#5).

 > I don't have a particular example (except MUMPS itself), but suppose I
 want to install versions of Mumps, SuiteSparse, SuperLU, ... not provided
 by macports - then I have to do the patching myself (or manually install
 metis 4). Metis 4 was the standard for more than 10 years when there was
 no development there; scientific codes are usually conservative in that
 you don't want to touch what works, so people do not easily change to
 Metis 5 (look at Mumps and SuiteSparse).

 Yes, I am very familiar with the community not wanting to update their own
 code (even when given the patches!) from being on the PETSc team. Barry
 has a way of convincing others to not pander to lazy scientists so I don't
 think it's very persuasive to (from what I can understand) not want to
 have a longer link line and especially use software outside the macports
 tree (which is not supported nor stable).
