The DEP '>=dev-libs/nspr-4.10.7' in www-client/firefox-37.0_beta1 is not sufficient and needs to be bumped to '>=dev-libs/nspr-4.10.8', otherwise the build will fail: configure:14522: checking NSPR selection configure:14622: checking for nspr-config configure:14657: checking for NSPR - version >= 4.10.8 configure: error: you do not have NSPR installed or your version is older than 4.10.8. *** Fix above errors and then restart with\ "make -f client.mk build" /var/tmp/portage/www-client/firefox-37.0_beta1/work/mozilla-beta/client.mk:361: recipe for target 'configure' failed
Thanks for catching this, fixed in-overlay. A new beta will be coming out shortly so I didn't revbump this ebuild.
