New description:

 Using 'port reclaim' produces the list below; when answering Yes, thus
 uninstalling them, and then running 'port upgrade outdated', they get
 reinstalled again. So somehow, there are some hidden dependencies that
 'port reclaim' does not see. Possibly they are related to the port
 lilypond-devel.

Comment:

 Presumably reclaim is designed to remove build dependencies since they are
 not needed after the port has been built. From the list you showed, cmake,
 flex, gmake, and pkgconfig definitely fall into that category. But if you
 then upgrade ports and need to build them from source, build dependencies
 will again be needed and will be reinstalled. This is as designed, though
 evidently not as you expected. It might be nice if MacPorts offered the
 option to keep build dependencies. And that option should probably be on
 by default if MacPorts is configured to buildfromsource always.
