> Typeslots.inc is listed in the .hgtouch file, so you might be able to work around by running “make touch” before building.

My initial issue is that "import ssl" fails with <class 'RuntimeError'>: invalid slot offset. This error is really strange and Google doesn't know it.

I probably missed something when I compiled Python, but I would prefer that Python build system detects such issues for me, rather than having to use workarounds.
