Yes. Install-time dependency behavior didn't change between c9 and
c11, and always should've worked.

I'm only referring to the options that control the locating of
dependencies for the easy_install command, so that build-time
dependencies are found from the same place as install-time
dependencies, during a subordinate build step. That's a pretty
narrow range of options and conditions. And the --find-links entries
will be merged with the parent's. --index-url and --allow-hosts, on
the other hand, should always be the parent's settings, and it's
arguably a bug that they're not already being honored.
(Apparently, not enough packages are using build-time dependencies
for the problem to have been noticed and reported before now.)
