Isn't this part of the first situation offered (RDEPEND+DEPEND, rather 
than RDEPEND|DEPEND)?

I don't think I understand the difference between the effects of these 
two options. Could you describe a scenario where one would make things 
possible and the other wouldn't? Here's my attempt from an ebuild dev's 
POV, not from an ebuild dependency POV:

The way I'm thinking, the RDEPEND|DEPEND case means an ebuild developer 
would have no idea which list would be used, so you'd have something 
like COMMON_DEPEND to describe the pkg_*-used dependency, which would be 
in both RDEPEND and DEPEND. This would allow both RDEPEND and DEPEND to 
have unique dependencies, which seems like it could be beneficial. It 
would probably require fixing the tree for packages that currently 
assume RDEPEND will be available, although I don't expect that many 
packages will have unique RDEPEND settings (mainly binaries).

I guess the RDEPEND+DEPEND case would save an ebuild dev the work of 
specifying the COMMON_DEPEND list, but other than that, I can't think of 
any benefits. It would force both RDEPEND and DEPEND to be installed for 
binpkgs, which sucks.

Thanks,
Donnie
