Please find attached an updated graphviz-1.7.15.ebuild.
Unfortunately, there doesn't seem to be a configure in the tarball, so
the ebuild might look a little funny because it uses autogen.sh instead
Besides the version update, the following was added:
2. conditional tcltk dependency
(Not sure if this works for portage tcl-tk-8.3.3, as the portage version
is broken. It doesn't install private headers. I submitted fixed tcl
and tk ebuilds to this list previously, and it works with those)
I have also attached a diff between the original and the new ebuild.
Created attachment 2 [details]
Created attachment 3 [details, diff]
commited, added depends on 25 too, so that I get notified when 25 is fixed.
