Description Michael E Harris 2006-09-29 12:55:02 UTC

From a discussion on the forums, a mod suggested a feature request for portage.  The thread is
http://forums.gentoo.org/viewtopic-t-502941.html

basically, i had an emerge world fail, during the process of updating profile and gcc, after 7 hours, because the current version of evas required the use flag png.  It would be nice if portage could check use flags and other environment factors (like required version of gcc/glibc, for example) for all packages about to be compile,  to make sure everything is sane before starting the world emerge.

Until bug 2272 has been fixed, we use built_with_use from the eutils eclass.  Portage already does non USE-based dependency checking.
