Version 0.6.41 has been out for a couple of months, and specifically incorporates the necessary fixes to enable the python bindings. Simply renaming the ebuild and uncommenting the relevant bits works.
Created attachment 202262 [details, diff] possible ebuild changes Attached is the set of changes I made to the ebuild - the biggest change is that I added USE=dii, since the pst2dii tool pulls in a lot of dependencies (gd, imagemagick, etc.) and the "Summation DII" format isn't necessarily useful to the majority of users. I also rearranged DEPEND and RDEPEND to more accurately reflect what seem to be the build- and run-time dependencies (I could be way off on that).
