For me (net-libs/xulrunner-1.9.0.5) using: --with-gecko=libxul-embedding seems to avoid the need for the gecko.patch checking for gecko version... 1.9 checking for XULRUNNER... yes ... liferea 1.4.23 Build Mozilla Plugin............ : yes Build WebKit Plugin............. : no Build GtkHTML Plugin............ : no
liferea-1.4.27 fixed this. --with-gecko=libxul works fine without any patches.
