When I try to install hal (with polkit/devkit and therefore eggdbus) on a fresh install it says "Failed Running automake !"
Created attachment 212545 [details] automake.out Attached the automake.out
... as you can guess from the log-output it helps to install gtk-doc first.
I've got the same problem as you, but installing gtk-doc didn't solved it. Any other guesses?
I could solve the problem with, unmerging the gtk-doc, adding the "doc" useflag and remerging the whole thing (gtk-doc and eggdbus). So without the doc useflag there shoudn't be a ENABLE_GTK_DOC in the automake file.
