boost@1.48.0_3+python24 build fails

[larryv (Lawrence Velázquez)]

I can successfully build the +python25, +python26, and +python27 variants. I haven't tried either of the Python 3.x variants.

I tried sifting through the log but gave up pretty quickly. I compressed it before attaching, since it was 25 MB.

I'm on OS X 10.7.2, with Xcode 4.2 and MacPorts 2.0.3.

So the problems are:

The Portfile specifies that we want python to be /opt/local/bin/python2.4, but the configure script appears to ignore this and use the command /opt/local/bin/python, or just python, which it then discovers happens to be version 2.7 (probably because that's what you've selected with "sudo port select python"). Then it can't make this work ("No working Python interpreter found"), falls back to nonsensical defaults ("include path: "/opt/local/Headers""), and then can't find the files it needs ("pyconfig.h: No such file or directory").

Well I don't have a bin directory under ${frameworks_dir}/Python.framework/Versions/2.4, so that would explain why it can't find python there. It does exist for 2.5, 2.6, and 2.7.

Hmm... I think the easiest thing to do is remove the support for Python 2.4 in the next checkin. Anything else would involve a lot more logic to the Portfile than I'm willing to put in.

So - unless someone volunteers to implement and test the patch, 2.4 will be removed in the next checkin.
