Revision: 143374
          https://trac.macports.org/changeset/143374
Author:   dstrubbe at macports.org

Log Message:
-----------
gromacs: Replace subport gromacs-double by variant gromacs +double, since there doesn't seem any good reason to want them both installed at once, and the current support for doing so is broken anyway.
