Hello. Please don't be too harsh if I got this wrong or if this looks
like whining :P
A lot of ebuilds seem to ignore the "X" USE flag and instead only have
"gtk", "qt" and the like. This should be declared absolutely wrong,
IMHO. When a program provides a command-line tool and a GUI tool, and
the GUI tool uses only one toolkit, then the USE flag should be "X".
"gtk" vs "qt" vs "fltk" etc should be used only in cases where a program
can be built with either of those toolkits. When there's only one
choice, then this doesn't make sense. Isn't this what the "X" USE flag
is there for in the first place? Having a package where, say, Gtk is
*not* optional having a "gtk" USE flag doesn't make sense. The X tool
of that package is optional, but Gtk is not optional for the X tool.
A Gnome user probably has "X gtk -qt" in make.conf, while a KDE user has
"X qt -gtk" in hope to have programs that support both Gtk and Qt being
built with the toolkit that is more native to his DE. When a package
has a GUI tool that is able to only use one of those toolkits, people
who have it disabled in make.conf will get no GUI tool at all even
though they have "X" in their USE flags.
I hope I was able to explain the problem (as I see it) correctly :P If
people agree with me, it might be a good idea for maintainers of
packages that behave like that to start using "X" as the USE flag that
controls building of the packages GUI tools.
Sounds sane. For correct usage lately the mplayer ebuild was rewritten
this way.
Might be good idea to open tracker for these and all bugs cced to it. So
interested persons can fix it.
Note for maintainers: qa bugs are considered as issue when adding new
packages. In longer perspective it is good to have them fixed, but you
don't have to proactively fix old packages. Writing this before people
starts complaining we are again filling lots of bugs.
@qa: any objections against me opening the tracker?
To sum up the issue:
use X wrap all other widget useflags if there is CLI interface
available, so if user don't want X usage for package he just set -X and
rest widget flags don't matter at all.

IMHO. USE="X" is for controlling X.org dependencies, not for avoiding
everything that deps on them, so I disagree.
I was under the impression that USE flags are for enabling/disabling
features, not for controlling deps. DEPEND and RDEPEND is, AFAIK, the
way to control deps.
