Some files needed for locale support in X11 are missing from the ebuild: /emul/linux/x86/usr/lib/X11/lib/locale/libs/common/* In emul-linux-x86-xlibs-2.2.1-r1 they are present. This causes emul-linux-x86-java-1.4.2.03-r1 to fail for some java apps or applets. For example the sun test applet crashes firefox-bin: http://www.java.com/de/download/help/testvm.xml Or /opt/java32/bin/policytool complains about "current locale is not supported in X11" and crashes then. Furthermore the library seems to look for the locales at the wrong place. When installing emul-linux-x86-xlibs-2.2.1-r1 (which had the missing files) this environment variable is needed to fix this: export XLOCALEDIR=/emul/linux/x86/usr/lib32/X11/locale/ May be the path could be compiled into the emulion library?
The locales got moved to /usr/share. If you have libX11 installed, you will have them.
