Bugzilla Bug 207569

* Overlay eclass overrides eclass from PORTDIR:
 * 
 *   '/usr/portage/local/layman/science/eclass/fortran.eclass'
 * 
 * It is best to avoid overridding eclasses from PORTDIR because it will
 * trigger invalidation of cached ebuild metadata that is distributed with
 * the portage tree. If you must override eclasses from PORTDIR then you
 * are advised to run `emerge --regen` after each time that you run `emerge
 * --sync`. Set PORTAGE_ECLASS_WARNING_ENABLE="0" in /etc/make.conf if you
 * would like to disable this warning.
