It is a new system. It is some documentations:
http://www.gentoo.org/doc/en/java.xml
http://www.gentoo.org/proj/en/java/java-upgrade.xml
http://overlays.gentoo.org/proj/java/wiki/Common_Problems

It is a command to check the environment:  /usr/bin/java-check-environment

This new environement is ~arch, so it is a lot of packages to add
in /etc/package.keyword. But other packages depend on it, and with time it will
be more.

With the new java config, it is 2 package, java-config-1 and java-config-2
1 is for 1.3 or 1.4 jdks, 2 for 1.5.

dev-libs/cyrus-sasl-2.1.22 use this new config.
In the ebuild, we find:
inherit eutils gnuconfig flag-o-matic java-pkg multilib
...
RDEPEND="...
	java? ( =virtual/jdk-1.4* )
...
pkg_setup() {

        use java && java-pkg_pkg_setup
	...
src_compile() {...
	myconf="${myconf} `use_enable java` `use_with java javahome
${JAVA_HOME}`"
	...
	# Bug #60769. Default location for java classes breaks OpenOffice.
        # Thanks to axxo@xxxxxxxxxx for the solution.
        cd "${S}"
        if use java; then
                jar -cvf ${PN}.jar -C java $(find java -name "*.class")
        fi
	...
	more for this bug, but it is to be relevant only for cyrus.



The first time I try to install this package, I get an error message telling me
to run /usr/bin/java-check-environment
So, I think at it is the java-pkg eclass that tell me that.

After following the java upgrade guide, it just worked.

It is a devel guide: http://www.gentoo.org/proj/en/java/java-devel.xml

But I thing at it will not help with this version of tuxguitar. Otherwise, we
have to do an ebuild for the source packages. I take a look on it. Tuxguitar
use ant and eclipse. I have the first one in my sytem, but not eclipse, and I
don't know which eclipse package I must install.
