That's a fair request. Last thing which I have to think about is whether we want this in python-r1, or a more general shebang replacement function in eutils. > >> 2. there are no equivalent functions to the python_get_* stuff > >> which are sometimes necessary for broken build systems or test > >> phases > > > > There is python_export().

Passing an option is just inventing a minigun to shot a mosquito. I will be happy to fix that whenever someone stumbles around that. If ever.

Ok, looking at redshift, I'm not really sure if we really need or even want to install implementation-suffixed scripts there. That's something to discuss. The main reason for implementation-suffixing of scripts is that distutils can mangle the scripts for various implementations (i.e. 2to3 them). The side reason is ability to force a particular implementation when no other suitable way is available (which is pretty rare). To be honest, redshift doesn't fit either. I doubt anyone will really need to put 'gtk-redshift-python2.6' anywhere, and both scripts will be identical. So it may be just enough or even better just to mangle the script to have 'python2' shebang. > >> example: x11-misc/redshift-1.7-r1 > > > > Thanks.

You again fail to see an interim solution which will solve the issue without much trouble, similar to one used for multilib. You let the build system work with the default implementation, then repeat install for remaining implementations. Of course, right now it's not supported by python-r1. I will think how to solve it in a simple way. -- Best regards, Michał Górny
