trackma-9999.ebuild:34 causes the configure phase to fail. I don't use the qt5 version either, so it fails when trying to remove something that doesn't seem to exist any more. So commenting line 34 and 37 in my case fixed the issue, but that's just a local change.
missing build.log, missing emerge --info.
Thank you for the report. Please recompile and *attach* the logfiles and paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket The logs must be part of the ticket, but not on external websites. 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.
