Basically the autoconfigure finds the first instance of python you have and tries to build the swig interfaces for the library. It seems we do not want the python interfaces based on no USES=python directive in the make. I tried to disable by adding --disable-python and then --disable-swig into CONFIGURE_ARGS but it doesn't accept these as options. I think this requires patching out python in the configure.ac file to skip these checks. I have python 2.7 as a couple things still need a limited install of it, but I don't have py27-swig. I'm not sure how to patch python out, or if its better to just make it USES=python3+ . ADOL-C wants python 2.7 first in the search, and even if PYTHON environment isn't set, which I confirmed with make -v PYTHON it finds it by checking known executable names of python. I will try some other things and post a patch if i can figure something out, but not sure which way the maintainer wants to go with python as a dependency here.
