Crawling through this forum most people seem to use macos as keyword.
Otherwise I've been told on the mailinglist that ppc-macos is the keyword.
On third hand - both are listet in packages.gentoo.org.
We recently switched from using the macos keyword to the ppc-macos keyword. This was due to the changes suggested by GLEP 22: http://www.gentoo.org/proj/en/glep/glep-0022.html. In the future, the official keyword will be ppc-macos. Right now, we are phasing out the macos keyword, it should be completely removed after the next installer is completed.
I just wondered, if the keyword searchbar on top of packages.gentoo.org
could be changed to ppc-macos, for successful searching of packages known
to run under osx?
