pkgng seems to be out of date?

[Ben Laurie]

$ pwd
/usr/ports/textproc/xml2rfc
$ make build-depends-list
/usr/ports/ports-mgmt/pkg
$ make run-depends-list
/usr/ports/lang/tcl86
/usr/ports/x11-toolkits/tk86

But...

$ pkg query '%n: %do' xml2rfc
xml2rfc: textproc/expat2
xml2rfc: x11-fonts/fontconfig
xml2rfc: print/freetype2
xml2rfc: x11/kbproto
xml2rfc: x11/libX11
xml2rfc: x11/libXau
xml2rfc: x11/libXdmcp
xml2rfc: x11-fonts/libXft
xml2rfc: x11/libXrender
xml2rfc: devel/libpthread-stubs
xml2rfc: x11/libxcb
xml2rfc: devel/pkgconf
xml2rfc: x11/renderproto
xml2rfc: lang/tcl-modules
xml2rfc: lang/tcl85
xml2rfc: x11-toolkits/tk85
xml2rfc: x11/xproto


a) Why so many more dependencies, and...

b) Why different versions of tcl/tk?

And ... how do I fix it?

BTW, I use portmaster to maintain my installed ports...
