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?
