emerge --info

Default python version is 3.7, set via eselect.

`emerge --info` is actually bigger, so i put it in the attachment instead. Here goes build log:

Thank you for the report. Please recompile and 
*attach* the logfiles as described on
https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket
Can hardly read the log if it is pasted to the ticket.

We need to have all information at hand before ticket assignment, so that the maintainer can look after it in one session with minimal number of callbacks.
Please reopen this ticket (Status:unconfirmed) afterwards.

Come on, all you have to do is remove '2_7' for PYTHON_COMPAT definition in ebuild. This bug is 3 weeks old and is really present about twice as much.
