Comment(by jeremyhu@…):

 Well technically, the protos are not required to run and are not linked
 against.  They are headers.

 Adding them to depends_lib is not the right solution.  It would be a hack,
 because you should be able to remove them, and they should be installed
 again when you try to build something that needs them.  depends_lib does
 not satisfy that usage.  depends_build does, but not in an optimal way.

 As it is now, php-gtk is expected to depends_build on xorg-xproto, and
 everything that gtk2 had in depends_build... but then THAT would over-
 depend on things... for example, some ports depends_build on autoconf, but
 only that port needs autoconf...
