Recent portage versions allow automatic recompilation with different USE flags. This ebuild should also make use of this property. * You need to build www-servers/apache with APACHE2_MODULES='dav dav_fs authn_file auth_digest authz_groupfile' * * ERROR: gnome-extra/gnome-user-share-0.41 failed. * Call stack: * ebuild.sh, line 48: Called pkg_setup * gnome-user-share-0.41.ebuild, line 44: Called die * The specific snippet of code: * die "re-emerge www-servers/apache with APACHE2_MODULES='dav dav_fs authn_file auth_digest authz_groupfile'" * The die message: * re-emerge www-servers/apache with APACHE2_MODULES='dav dav_fs authn_file auth_digest authz_groupfile' * * If you need support, post the topmost build error, and the call stack if relevant. * A complete build log is located at '/var/tmp/portage/gnome-extra/gnome-user-share-0.41/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/gnome-extra/gnome-user-share-0.41/temp/die.env'.

You mean EAPI=2 use-deps? It's not as simple as it seems. Will be fixed for 2.26.
gnome-user-share is in the tree. If you tell me that you have a patch that is tested and works, I'm fine with including it. I'm not sure (pretty sure of the opposite in fact) EAPI=2 allows us to use IUSE_EXPANDed use flags in USE dependencies.

Even if it works, portage will tell the user to enable the USE flags instead of the modules. Which is plain wrong.
alright, IUSE_DEFAULTS not IUSE_EXPAND aware, maybe we should forward this to portage devs ?
Hi Zack, could you comment on comment #4 ? Is this a simple wontfix or is it possible that portage will support this in the future ?
I guess we're talking about bug #258371. For now, the best you can do is EAPI=2 USE deps and either set the flags via IUSE="+flag" or in profile package.use.

It wouldn't say that it's entirely "wrong", because it will work enable the corresponding USE flags such as USE="apache2_modules_dav". Portage will correctly generate the APACHE2_MODULES value to be consistent with USE settings. Moving forward, it's not a bad idea to add support to portage to generate special output for USE_EXPAND flags.
gnome-user-share 2.28 ebuilds uses EAPI 2 for that now. Probably not the most elegant way of writing such deps but it seems to work just fine.
