I emerged emacs-cvs and read many of the messages the scrolled by. When I saw the configuration summary, I noticed that all of my USE variable parameters had been properly included in the configuration except for Xaw3d. Shouldn't the USE=Xaw3d build dependencies on that package and install it and configure software like emacs-cvs to use it? Reproducible: Always Steps to Reproduce: 1. edit make.conf and include Xaw3d in USE= 2. emerge -v emacs-cvs 3. read the messages and note the configuration summary. 4. (as far as reproducibility goes, I only did this twice, and I did not unmerge before emerging the second time. The second time is when I captured the configuration summary from the text that scrolls by). Actual Results: lots of text scrolls by, including the configuration summary where included packages and enabled options are summarized (the results of a ./configure --... command) Among other lines, this one is the offender: emacs uses Xaw3d: No pasted from output: ...lots of text... # emerge -v emacs-cvs checking for mbstate_t... yes checking for C restrict keyword... __restrict checking for C restricted array declarations... yes Configured for `i686-pc-linux-gnu'.

You have the gtk USE flag selected. I/we arbitrarily chose for gtk to have higher precendence than Xaw3d. If you want to use Xaw3d, make sure the gtk USE flag is not selected when installing emacs-cvs, either by setting environment variables or by configuring emacs-cvs-specific USE flags in /etc/portage/package.use.
Marking as INVALID.
What is done in the emacs-cvs ebuild is standard practice for ebuilds; however, i may be desirable for ebuilds to simply give an error in the case that confliting USE flags are selected, so that the user is not faced with arbitrary behavior automatically. The user would then have to use either environment variables or a per-package USE flag configuration so that conflicting USE flags are not specified. Prior to per-package USE flags, this type of behavior would be highly inconvenient. Now though, it may be more desirable. Until it is approved as a useful policy, however, I will not change the emacs-cvs ebuild.
