The recentmost not masked libreoffice version (app-office/libreoffice-4.2.6.3) has app-text/libodfgen dependency set as "=app-text/libodfgen-0.0*" but in fact it requires at least version 0.0.3 (as configure script says).
I'm not sure that the dependency should be ">=app-text/libodfgen-0.0.3" because the library has the "0.1*" versions and I don't know whether they are acceptable for the libreoffice.
I get the same error building app-office/libreoffice-4.2.6.3 against libodfgen-0.0.2 Building against libodfgen-0.0.4 doesn't cause the configure issue and the build completes without error. checking for ODFGEN... no configure: error: Package requirements (libodfgen-0.0 >= 0.0.3) were not met: Requested 'libodfgen-0.0 >= 0.0.3' but version of libodfgen-0.0 is 0.0.2 Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables ODFGEN_CFLAGS and ODFGEN_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. !!!

Sigh. It helps to occasionally update world. Fixed.
