Created attachment 291133 [details] New ebuild Please bump doxygen-1.7.5.1 which has been released on 08/21/2001. It seems to me that the only thing that needs to be changed is the dot-eps patch.

Thanks for the updated patch. Looks like the native Tcl support was added in 1.7.5 so that patch was also removed.
