You're receiving this canned (template-based) bug report because I found a problem with a package during my tinderbox run.
The package in question is running automake (and most likely other autotools) during compile phase by maintainer-mode. You can see in my blog post in the URL field why that's a problem, and how to address the issue, but in general, you don't want maintainer-mode rebuild during compile phase, especially since it can cause multiple run of econf.
The causes of maintainer-mode rebuild are various, but most likely it's because of a patch that changes Makefile.am or configure.ac/in and don't rebuild autotools properly. The way to fix this is almost always to inherit autotools eclass and run eautomake/eautoreconf (as needed; eautoconf should only be used when automake is not involved, which is not the case here) during src_unpack phase.

I don't see "maintainer" mentioned in the log. Seems like it works fine to me. Reopen with more specific information.
maintainer-mode does not say "maintainer", you have to look for calls to "missing --run":
cd . && /bin/sh /var/tmp/portage/games-engines/kwest-1.1.1/work/kwest/admin/missing --run aclocal-1.9
(check my blog post in URL for details)
^ kwest was removed from portage, so closing this bug
