Disclaimer: this bug has been filed in a semi-automated manner. When emerging the package dev-libs/ppl-0.11.2-r1, the following elog messages are displayed: * If you use gcc-config to switch to an older compiler version than * the one PPL was built with, PPL must be rebuilt with that version. * * In both cases failure to do this will get you this error when * graphite flags are used: * * sorry, unimplemented: Graphite loop optimizations cannot be used * Such messages should only be displayed when the package is a new install. These situations can be checked in the ebuild as follows: if ! has_version 'dev-libs/ppl'; then See the tracker bug 440214 for more details.
There's nothing about this message that applies only on first install.
Is this specific to ppl? If not, should probably be added to gcc updating guide instead
I'm not changing it. Go away.
