That requires a rejigging / enhancing / rewriting of the the (Debian) build file to ensure that any files needed by both end up in a -common package, that the serial build ends up in a package of its own, that the parallel build ends up in a package of its own and that all corner cases of upgrading from (current) serial to (new serial), or new parallel etc pp are covered. Plus all switches between and all possible transition. All doable, just a lot of patient nitty gritty work. And I just don't have the time. I am truly sorry. I _could_ change the standard build to always use openmpi. May open yet another can of worms, but at least it is less involved. Dirk -- http://dirk.eddelbuettel.com | @eddelbuettel | edd(a)debian.org
