Bugzilla Bug 104785

the summary says it all:

checking for gnome-doc-utils >= 0.3.2... Requested 'gnome-doc-utils >= 0.3.2'
but version of gn ome-doc-utils is 0.2.0
configure: error: Library requirements (gnome-doc-utils >= 0.3.2) not met;
consider adjusting t he PKG_CONFIG_PATH environment variable if your libraries
are in a nonstandard prefix so pkg-co nfig can find them.

upgrading to 0.3.2 of course fixed this
