# problem with the Erlang build procedure is that it only checks if
# javac is in the regular path - and then assumes that all of the jdk
# utilities is in the path as well. The only way to make sure that
# this is the case (that I could think of at least) was to make sure
# JAVABINDIR is added to the PATH, using the *_ENV macros.
