You missed the point. If I install tool X, then I want the macports version of X. Overriding the system X. If tool X needs to install tool Y that might override the system Y, then use the tool Y from tool X, but the system Y otherwise. This can be done simply, by having the macports directory at the END of the path (so that system tools override macports tools), having macports programs call the macports utilities directly (instead of relying on the path), and having a generic_select program that in activated on all requested installs. So, if I install macports perl, then perl_select makes macports perl my perl. And, since "perl" comes with a bunch of utilities (cpan, etc), those are also selected to be the macports version. This way: 1. If something does not exist in the system, but is provided by macports, it's available (end of path). 2. If something was added by macports, but not requested, it doesn't get in the way of the system. 3. If something in macports needs a specific version, it gets it. 4. If something was requested of macports, then the macports version is used. >> So, for any program with a local version and a system version, we need >> a generic_select program. > >How is having a *_select problem going to be easier for people than using the >full path to the >binary they want or having the user modify their $PATH to do >what they want? Because the select is done by macports when installed; the user just runs the program, and now gets the macports version. -- Political and economic blog of a strict constitutionalist http://StrictConstitution.BlogSpot.com _______________________________________________ macports-users mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macports-users
