Compiling with Automake 1.10

Right now Liferea doesn't build with Automake 1.10 (it works up to 1.9.x). When running configure you get errors like these:

configure.ac:178: warning: macro `AM_GCONF_SOURCE_2' not found in library

I've searched the net for answers and tried a lot of thing, but couldn't find much on the issue. Does anyone reading the blog know about what to do to migrate from automake 1.9 to 1.10?

Update: After a hint from Adrian Bunk the solution to the problem above is to ensure a correct libtool installation. Reinstalling the libtool package did solve the problem for me.
