Using python before it is selected?

[Jeremy Lavergne]

> Sorry, I'm not following.  The first time my port is installing, it is using depends_lib to pull a bunch of py26-* modules.  But the "port select --set python python26" command hasn't happened so effectively, there is no python available when configure for my port starts running.  The software is there but select hasn't done its magic.

Does your configure not allow you to set a specific python, maybe with an ENV or replacing the shebang? If not, you can have MacPorts patch it throughout your configure ${files} before you run it.:

    foreach file ${files} {
        reinplace {s|/usr/bin/env python|${prefix}/bin/python2.7|} ${worksrcpath}/$file
        reinplace s|/usr/bin/python|${prefix}/bin/python2.7| ${worksrcpath}/$file
    }
