qt5-qtwebkit question: ruby193 vs ruby200

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Why does qt5-qtwebkit's buildlink3.mk contain:

BUILDLINK_DEPMETHOD.ruby=       build
.include "../../lang/ruby/buildlink3.mk"

?

I only took at look at this file because qt5-qttools has a weird
buildlink problem:

===> Creating toolchain wrappers for qt5-qttools-5.2.0nb4
ERROR: ruby193-base>=1.9.3 is not installed; can't buildlink files.
*** Error code 1

Checking up:

# cd /usr/pkgsrc/x11/qt5-qttools
# make show-buildlink3
...
qt5-qtwebkit
...
    ruby200-base
        pthread
        dl


So it looks like qt5-qtwebkit is built against ruby200, but ruby193 is
pulled in from its buildlink3.mk for some reason.

Does anyone have ideas for the fix?
