    install python2.4 on FreeBSD and keep using python2.3

    Hi,

    I have python2.3, installed from port /lang/python long time ago. The
    current version is 2.4, but I'd rather have two python versions,
    instead of upgrading.
    Is there maybe a way to somehow link installed python to
    /lang/python2.3 port, and then upgrade ports and install /lang/python
    as a new (2.4) version, without upgrading?
    Or am I missing something and the things are much easier? I am not a
    FreeBSD guru and it's my first python upgrade... thanks!

      Yes, you can have several versions installed in different directories.

      Many people make /usr/local/bin/python or /usr/bin/python a link to the
      default version they choose for the machine.

              You can't install from ports and keep multiple versions around. Well,
              at least not easily. You'll have to install from the Python
              sources. If you haven't changed LOCALBASE, then installing from
              sources will overwrite the things installed in /usr/local/bin, the
              python manual page, and the emacs python-mode file (at least, that's
              what's installed by the Python port that isn't in a version-specific
              file). As others have said, you can work around that with the --prefix
              argument to configure when you build python.
