pkgsrc: misc/yelp configure failure

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

Hi,

misc/yelp configure fails with:

[...]
checking for gawk... (cached) /usr/bin/awk
checking which gecko to use... libxul-embedding
checking manual gecko home set... Package libxul-embedding-unstable was
not found in the pkg-config search path.
Perhaps you should add the directory containing
`libxul-embedding-unstable.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libxul-embedding-unstable' found
checking for compiler -fshort-wchar option... yes
checking whether to enable C++ RTTI... no
checking whether we have a gtk 2 gecko build... configure: error: This
program needs a gtk 2 gecko build
