Just fork the repository, commit things and create a pull request. I will pick it up and merge.

At the moment, OI has only python 2.6, which sucks. Therefore, I am working on bringing new pkg, which is needed for publishing python 2.7. Once that gets published, plan is to make it the default version.

Speaking of packaging look at any python component. It should reside under python directory, There should be 2 p5m files (e.g numpy.p5m and numpy-26.p5m, numpy.p5m creating conditional dependency on a numpy-26. Just ignore -PYVER.p5m for now).

Bitness is something packager has to consider. If there is a point in delivering a 64 bit package, then do so.

I have looked at gdb yesterday and the component needs removing studio specific compile flags and make it builadble by gcc. Also test suite should pass all tests if possible to test package functionality.

Great, if you mind sharing just create a pull request.
