[Engine-devel] Rebuild ovirt 3.2.1 success, but lost i18n support

Hi all, I just rebuild ovirt-engine 3.2.1 according to http://www.ovirt.org/Building_oVirt_engine , it work fine, but I could not choose the language, it always display U.S. English UI. Could you give me a hand, how can I enable GWT's i18n support, or something is wrong in my building ENV? Thanks in advance. -- Bests, An Yang
