Bugzilla Bug 128391

"emerge =app-editors/emacs-21.4-r3" failed because it did not emerge libXp
first. A workaround is to do "emerge libXp =app-editors/emacs-21.4-r3" but that
should of course have been automatic.

# emerge emacs -pv

These are the packages that would be merged, in order:

Please provide the error output from when you tried to emerge
=app-editors/emacs-21.4-r3?  I had a quick look for the dependency

Seeing the error messages you encountered would help me.

Note that "equery d libXp" shows "x11-libs/libXaw-1.0.1" and emacs has Xaw3d in
the use flags (see original post).

So it seems Emacs should have x11-libs/libXaw as a dependency regardless of
whether Xaw3d is in USE.  Would you agree with that?

I have just posted:

http://bugs.gentoo.org/show_bug.cgi?id=133515

It appears to be related although not identical.

related to bug 133515 I think, that has been fixed
