htmldoc requires xfree even the "-X" flag is set, look's like the ebuild does not catch this (as far as i understand, "-with-x --with-gui" will always be used as configure parameters)... we use htmldoc for serverside conversion of html documents, and xfree is not really welcome on the server ;)
Created attachment 18312 [details, diff] patch to split out X from htmldoc. I've added an fltk USE flag that I found in the alsa-patch-bay ebuild.
fltk is a local use flag for alsa. should be handled another way.
