No answer? Nobody ever had that problem? :(
What I think I'll do if this isn't feasible is depend arbitrarily
on one of the alternatives and add a comment in the rockspec, but
this is not really satisfying...
If there is no solution to this maybe we could add one. For instance,
we could maybe have that syntax:
dependencies = {
"lua >= 5.1",
{"md5", "crypto"},
}
meaning: "If you have either md5 or crypto it's OK, otherwise install md5."
Thoughts?
