>Description:

although those ports work perfectly fine without devel/pkgconfig,
they record a run-time dependency on this port.

This has multiple nonconstructive effects:

- users are forced to fetch, build and install ports they don't
  need.

- users are hindered to delete a package they don't need

- users a forced to update packages that don't use pkgconfig
  when pkgconfigs version number is bumped.

Generally in FreeBSD dependencies denominate build- or runtime
requirements. So ports that *install* .la files don't run-time
depend on devel/libtool, ports that install a C++ library compiled
with gcc33 do not run-time depend on lang/gcc33.

I would expect client applications that require pkgconfig to build
to build-depend on devel/pkgconfig, and only if they actually use it
during runtime to run-depend on this port.

>How-To-Repeat:
>Fix:

remove
USE_GNOME=	pkgconfig
from textproc/libxml/Makefile
