And I've seen some ports even aren't compliant with hier(7), too. ...then, Tim Kientzle wrote: > A better approach might be to simply fob it > off on the user, i.e., > > # pkg_install foo-1.5 > Warning: foo-1.5 requires bar-2.3, you have bar-1.7 installed. > Proceed? [Y/n] In my opinion, user should be bothered with choices *only* when, like in this example, when dependency isn't *at* *all* satisfied. User definitely should *not* be bothered when differences are irrelevant to the functionality. E.g., ask only when bar-1.7 is installed and 2.3+ required, not when bar-1.7 is installed and say 1.4.1+ is required. I think dependencies could / should also have *upper* revision limit (library interface change, e.g.). And there could also be functionality of system-wide dependencies updating (isn't there one?) I've seen interesting concept of version number processing by D.J.Bernstein (called slashpackage, I believe).
