The ebuild of of any version of app-office/libreoffice is missing a required use flag of dependency x11-libs/cairo. If cairo is built without the X use flag app-office/libreoffice-3.4.3.2-r1 fails with the error messages "Please define fast prop retrieval for your platform!" and "Native API needed.". app-office/libreoffice-3.5.0.1 fails and complains about missing "cairo-xlib.h". cairo-xlib.h is provided by cairo compiled with X use flag. Reproducible: Always
Fixed in cvs.
