I do not think that it is stuck in the bashrc itself, but something that
happens in the
bashrc makes the emerge python process not realizing that everything finished.
These are
the interesting running processes after the command
`ebuild /usr/portage/net-mail/dovecot/dovecot-2.3.10.1.ebuild qmerge`
gets stuck (I cannot see any bash still running, that's why I assume that the
bashrc itself finishes):
