Merging www-client/epiphany-extensions-2.20.3 fails on automake --add-missing --copy --foreign with following error in /var/tmp/portage/www-client/epiphany-extensions-2.20.3/temp/automake-4808.out ***** automake ***** configure.ac:34: version mismatch. This is Automake 1.10.1, configure.ac:34: but the definition used by this AM_INIT_AUTOMAKE configure.ac:34: comes from Automake 1.10. You should recreate configure.ac:34: aclocal.m4 with aclocal and run automake again. Reproducible: Always Steps to Reproduce: Similar to bug #207114, Removing line cp aclocal.m4 old_macros.m4 from epiphany-extensions-2.20.3.ebuild fixes the problem.
I removed the copy of aclocal and strangely it still works. I wonder why it was introduced in the first place but it seems fixed now. If not feel free to reopen this bug.
