# Additional dependencies for building:
#   unzip: extract OpenJDK tarball
#   xalan/xerces: automatic code generation
#   ant, ecj, jdk: required to build Java code

# NOTE: we depend directly on dev-java/icedtea6 instead of virtual/icedtea-jdk
#       because if the virtual is not installed, portage will try to satisfy
#       gnu-classpath-jdk instead
#       it would be possible if the order was reversed but then there are
#       circular deps instead...
# NOTE: we need to depend also on virtual/jdk unless the eclass won't switch VM
