MacPorts almost never touches /usr. The "port select" command creates symlinks under $prefix, according to rules specified by the relevant *_select port. For instance, python_select (used by "port select --set python") creates these files: https://trac.macports.org/browser/trunk/dports/sysutils/python_select/files/base > select —summary > > Name Selected Options > ==== ======== ======= > awscli py34-awscli py34-awscli none > maven maven3 maven3 none > mysql mysql56 mysql56 none > pip none none > python none python26-apple python27-apple python34 none > python3 none python34 none > > Why is python in more than one group? The python, python2, and python3 groups are distinct from one another and install different symlinks. This is an attempt to adhere to PEP 394 as best we can. https://trac.macports.org/browser/trunk/dports/sysutils/python2_select/files/base https://trac.macports.org/browser/trunk/dports/sysutils/python3_select/files/base https://www.python.org/dev/peps/pep-0394 > If I call python from the command line it launches the python3.4 even > though port select shows that none is selected. > > port select —set python python34 yields an error: Selection ‘python34’ for > ‘python’ failed: symlink: /opt/local/etc/select/python/current -> python34: > file already exists. This problem was brought up previously on this list. You may have uninstalled python34 at some point while it was selected; the "port select" code doesn't handle this properly and leaves dangling symlinks. Can you run this and tell us what it returns? (If you see any messages about permissions, run it again with "sudo".) $ find -L /opt/local -type l vq _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-users
