D'oh. My earlier snip was also from the same eclass. For some reason I
just didn't look hard enough to see if those variables were defined in
the same file. Thanks!

Not exactly what I meant. But your answer above already solve the
problem: in my opinion it is one thing to "fall in line" for each
package (in this case, enlightenment) separately, and a completely
different thing to just make the assumption that 9999 version numbers
will never be used (practical experience aside, of course :) ).

Okay, so since I run a mostly ~x86 system, I can just keyword mask e17
if I don't want those packages. 

I will probably just suck it up and install e17 anyway: I use DR16 on
my stable desktop, but mostly fvwm on my testing laptop. I tried DR17
a bit back on my laptop, but way back then something in the chain of
DR17-Xorg-my ATI video card doesn't like the eye candy. I'll give it
another try to see if it has miraculously gotten better. (Though I am
rather fond of my fvwm setup now; I just wish I can figure out a way
to get transparencies to play nice with some of the quirky stuff I
have in my configs.)

I've read man 5 ebuild and the HOWTO on the gentoo.org page. Haven't
seen Ciaran's wiki document yet. I think (if I have some time) I
should take your advice and just read the eclass and the ebuilds. I
read about ebuilds when I was trying to write a ebuild myself--3 days
into the effort, something still wasn't working, and someone else beat
me by putting one into sunrise. C'est la vie. 

Thanks

PS, I'll give e17 another look. Perhaps I'll take you up on your offer
for the overlay.
