# Additional dependencies for building:
#   zip: extract OpenJDK tarball, and needed by configure
#   xalan/xerces: automatic code generation
#   ant, ecj, jdk: required to build Java code
# Only ant-core-1.7.1-r2 and later contain a version of Ant that
# properly respects environment variables, if the build
# sets some environment variables.
# ca-certificates, perl and openssl are used for the cacerts keystore generation
# xext headers have two variants depending on version - bug #288855
# autoconf - as long as we use eautoreconf, version restrictions for bug #294918
