. Actually create a valid BUILD_DEPENDS for the bootstrap JDK instead of
  just skipping it.
. Make the default bootstrap JDK diablo-jdk16 rather than diablo-jdk15.
  We should actually try and get this from bsd.java.mk somehow.
. Fix some portlint warnings:
  . No quotes for RESTRICTED and NO_CDROM.
  . Use variables for executables rather than the raw names.
. If DISTFILES are missing then print out the instructions to get them
  nicely formatted and error out rather than trying to use IGNORE and
  resetting ECHO_MSG.
. Fix some grammar errors in various messages printed out by the port.
