It looks like both OS X's Homebrew and Debian's Apt deal with this by
just having the packages conflict. Homebrew definitely warns about the
conflicts, when it sees you trying to install both packages, and I would
assume Apt does too.
I'm guessing setup-*.exe doesn't have the ability to detect and handle
this sort of conflict, but I can see a bunch of alternative options:
- Do nothing for now and deal with the problem as and when someone
ITPs GNU parallel.
- Add detection for this sort of conflict somehow, and refuse to allow
users to install conflicting packages.
- Document the conflict in release announcements but otherwise do
nothing, and allow the packages to overwrite each other if both are
- Rename moreutils parallel (e.g. `mparallel`) so it doesn't conflict.
- As and when GNU parallel is packaged, rename it (e.g. `gparallel`)
so it doesn't conflict.
- Just refuse to package one or the other for Cygwin.
I'm leaning towards either doing nothing and leaving it as a problem for
the future, or renaming moreutils parallel now, but I'd be very
interested in the list's opinion.
