#50225: py27-matplotlib - build failure ------------------------------+-------------------- Reporter: davideproment@… | Owner: sean@… Type: defect | Status: closed Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: invalid | Keywords: Port: py-matplotlib | ------------------------------+-------------------- Comment (by sean@…): MacPorts manages everything under `/opt/local` so installing something by hand into that directory will confuse it. Like it did in your case. If you need something outside of MacPorts for python, then the easiest option is to use a `virtualenv`. Optionally, you could submit a portfile to add that package. In your case, I'd start by uninstall whatever you installed with `pip` and then trying the upgrade again. -- Ticket URL: <https://trac.macports.org/ticket/50225#comment:6> MacPorts <https://www.macports.org/> Ports system for OS X
