Is an interesting idea, and I do know other packages that would benefit. What I'e usually done in these cases is: Conflicts: lammpi (< 7.1.2-1000) I'm not sure fink (or even dpkg and apt themselves) are smart enough to figure out the correct ordering when asked to install both, but at even if not, the error message is clearer. Instead of "lammpi is installed, you're trying to install openmpi and they collide", it's something like "you have lammpi-7.1.2-1 and are trying to install something that conflicts with that version of it." That might lead user to look at upgrading his lammpi version (which solves the problem) instead of having no clue how to go about solving the conflict. dan -- Daniel Macks [EMAIL PROTECTED] http://www.netspace.org/~dmacks ------------------------------------------------------------------------- Take Surveys.
