Doxygen does invoke dot with -Tps to generate files which it stores as *.eps. Current versions for media-gfx/graphviz do support a dedicated -Teps flag to produce Encapsulates PostScript. This has the benefit of avoiding bug #282129. According to the ChangeLog the flag is present since 2.20.0 from 2008-06-20, so all unmasked graphviz versions in portage should work, although it would still make sense to bump the dependency in the ebuild from 2.6 to 2.20. The issue doesn't seem to be resolved in the current trunk sources, so this fix is needed even when doxygen gets bumped to 1.6.0, as bug #269961 requests. I'll attach a patch and try to report the thing upstream as well.
Created attachment 201816 [details, diff] Use -Teps instead of -Tps
Reported upstream as http://bugzilla.gnome.org/show_bug.cgi?id=592516
1.5.9 is now the latest ~arch, and uses the -Teps patch (along with 1.6.0, which is currently masked). Okay to close?
