Hi, There are two cases: - packages that only work with a specific version of Ruby, e.g ruby1.8. Those must use /usr/bin/ruby1.8 in shebangs, and depend on ruby1.8 - packages that work with any ruby implementation. Those must use /usr/bin/ruby in shebangs, and depend on ruby | ruby-interpreter So yes, you are correct: what gem2deb currently generates is suboptimal (though not a serious problem right now). - Lucas -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
