A dependency is considered satisfied if the dependency is installed,
not if it is activated. I think this should be considered a bug.
You encountered a problem unrelated to the separation of dependencies
into runtime (_run), linked against (_lib), and build time (_build)
dependencies.

Have various dependency questions here. I couldn't find info on

Why do we have depends_lib, depends_build and depends_run? Why not
just a single "depends"? Why does it matter which phase requires
the other software? Isn't it enough to know that the other software
is required at some point, and so MacPorts should install that
other software first?
What are these three keywords supposed to denote? I thought
"depends_lib" was for libraries a program links with (e.g.
gettext), "depends_build" was for things only the build system
needs (e.g. pkgconfig) and "depends_run" was for binaries that need
to be present at runtime (e.g. I have no idea).
To this end, I tried adding "depends_build pkgconfig" to a port
that needs it (graphviz), and then I forcibly deactivated the
installed pkgconfig to make sure that worked. Well, it didn't.
"sudo port install graphviz" proceeded to build just graphviz,
without attempting to activate the required pkgconfig first. If, on
the other hand, I completely uninstalled pkgconfig first, it then
correctly installed pkgconfig when I tried to install graphviz. Why
does a deactivated port seem to satisfy the dependency? That should
not be.
Hm... could it be that the point is that it should be fine to
uninstall a build dependency later, but uninstalling a library or
runtime dependency would cause installed ports to fail? Is that the
reasoning?
