tigervnc fails because of libXfont2

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
I'm trying a bulk build of HEAD (with native Xorg on netbsd-9) and tigervnc is
being prefailed becase libXfont2 is prefailed (tigervnc was building in
the previous release).
libXfont2 is prefailed with:
PKG_SKIP_REASON="Package set is using native X11 component"

I tried removing
BUILDLINK_ABI_DEPENDS.libXfont2?=               libXfont2>=2.0.6nb1

(added after the previous stable release) but it didn't help.

A direct build fails with:
=> Full dependency libgcrypt>=1.6.0: found libgcrypt-1.10.1

It seems that tigervnc ends up with a dependancy on libXfont2 even trough
there is one in base. Other X11 dependancy don't have this issue.

Any idea ?
