I have a shell script that I run when I go to bed called good-night and part of it that pertains to Macports goes like this: #!/opt/local/bin/bash cd "~/base/" && /opt/local/bin/svn update && PATH=/bin:/sbin:/usr/ bin:/usr/sbin ./configure --enable-readline && /usr/bin/make && /opt/ local/bin/sudo /usr/bin/make install && /usr/bin/make clean && /opt/ local/bin/port -v selfupdate && /opt/local/bin/port -fvdRnu upgrade outdated && /opt/local/bin/port -fvdR clean --all installed && /opt/ local/bin/port -fvdR uninstall inactive && /opt/local/bin/port -fvdR clean --all uninstalled Your thoughts please.

(a novice question)
I installed a package (py25-matplotlib), had some trouble with using it, then did a port selfupdate,
then upgraded the package. In the process, a number of packages were deactivated.
For example, it looks like I now have two copies of python25, numpy, 3 copies of libpng, etc.
How can I uninstall these now (to clean up and save disk space)?
For example port uninstall python25 @2.5.1_2+darwin_8 says that I cannot uninstall this (deactivated) python because other things depend on it.
Most of those things are things that I'm actively using (py- readline for example).
should I uninstall and reinstall all of these? If so, it seems like upgrading is a bad strategy, one can save work by uninstalling and reinstalling?
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.
