I don't like this as-is, as it does prevent the introduction of the
"runtime/devel split" that has been so greatly desired on, say, HPCs.
However, if a granular DEPENDS could be introduced (speculating here), you
could fix this issue.

Let's say the package is "foo" and there is a "foo-lib" runtime subpackage
being generated with it.  They depend on "bar" for compiling, and "bar-lib"
for runtime (and, implicitly, compiling).  So:

DEPENDS.foo=		bar>=1.0:../../foo/bar
DEPENDS=		bar-lib>=1.0:../../foo/bar

Here, DEPENDS is for the main package "foo" and its subpackage "foo-lib",
but DEPENDS.foo only applies to the main package "foo".  Hence, from binary
packaging, only bar-lib is needed if foo-lib is installed.

Effectively, the DEPENDS.foo acts like a BUILD_DEPENDS to foo-lib, and could
even be recorded as a @blddep in its +CONTENTS if you so desired.
