Welcome to MacPorts! The message you're referring to is misleading. It says that this specific version of the port cannot be uninstalled because other ports depend on it. In fact, MacPorts has no concept of depending on a specific version of a port, so the message should just say that other ports depend on that port. And since you already have a newer version of that port installed, there is no problem with uninstalling the older version. MacPorts is just being overly cautious. You can force the uninstallation as Paul said: sudo port -f uninstall python25 If you already know when you upgrade that you want to uninstall the older version, you can use the -u flag: sudo port -u upgrade python25 This will fail if any other ports depend on python25, with the same error message as discussed above. So you need to force it. But forcing the upgrade of e.g. python25 also forces the upgrade of all ports that python25 depends on, possibly multiple times. This is not what you want. So if you're going to force an upgrade, always use the -n flag with the -f flag to indicate that you do not want the recursive port upgrade feature: sudo port -nfu upgrade python25 Yes, this whole situation is a little less than ideal, but it's what we have right now. _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macports-users
