openoffice-4 dist file missing; openoffice.org-3 fails to extract

[Gary Aitken]

Hi all,

Trying to build either of these:
  openoffice-4
  openoffice.org-3

For openoffice-4, I get:
  Requires distfile: ApacheOpenOffice.ext_sources.4.0.1.r1524958.tar.bz2
      doesn't seem to exist.
  It's not clear to me from the build message where 
    ApacheOpenOffice.ext_sources.4.0.1.r1524958.tar.bz2
  is supposed to be;
  I don't see it at 
    ftp.freebsd.org/pub/FreeBSD/ports/distfiles/openoffice

For openoffice.org-3 I get:

  ===> Fetching all distfiles required by openoffice.org-3.3.0 for building
  ===>  Extracting for openoffice.org-3.3.0
  => SHA256 Checksum OK for openoffice.org3/OOo_OOO330_m20_source.tar.bz2.
  => SHA256 Checksum OK for openoffice.org3/ext_sources.20110129.tar.bz2.
  => SHA256 Checksum OK for openoffice.org3/unowinreg.dll.
  tar: Unrecognized archive format
  tar: Error exit delayed from previous errors.
  *** [do-extract] Error code 1

Has anyone built either of these successfully recently?
If so, what's the magic?

Thanks,

Gary
