This is an 'addendum' to my previous i386 buildnotes to cover the 
building of openjdk7 on 64bit DragonFly.

- 1.6 required a hack to the pkgsrc 'gcc' wrapper
  to -I the correct directory for freetype (workdir-include/freetype iirc)
  as freetype's include itself is mulitplexed between 1 and 2, 
  and so has another level of nesting not matched in '-I' - 
  basically, to fix:
    - bmake configure
    - hack gcc wrapper to -I correct directory
    - bmake 
    - if you see bad errors w/r/t freetype, ensure directory is correct,
      remove related $WORKDIR dotfiles newer than the configure one to
      fool pkgsrc into resuming the build, and repeat
- from there, pkg_alternatives didn't work for the 1.6jdk package
  so - review the configuration for 1.5 when enabled, and clone
  (IIRC this basically required making some symlinks .. 
   pkg_alternatives default jdk1.5, ls -l /usr/pkg/ looking for symlinks
   should do it - etc.)
- x64 build required hacking hotspot/make/bsd/makefiles/defs.make.orig
  to understand 'x86_64' as a `uname -m` output rather than amd64.
