When configuring options for graphics/kipi-plugins-kde4, saved options are not taken into account. All options except for DOCS and NLS are unset.
Ouch! This was caused by the conversion to USES=metaport :-(

Revert USES=metaport conversion, again.
bsd.port.pre.mk and Makefile.common were being included before the many
options were being defined. Some of the options depend on Makefile.common to
be defined though, so for now revert the USES=metaport conversion to get
things back to a working state while a proper fix is devised.
