Created attachment 356188 [details, diff] ebuild diff AFAICS python is used only for tests here, and that's what I assumed hacking the ebuild. Please review the patch and either commit it, or let me know that I can commit it. Thanks.
Looks good to me. Feel free to commit this. Thanks.
Did one more test and Python is rather a full-time build dep. Fixed, re-tested and committed now.
