        Oh dear - something failed during the build - sorry !
  For more help with debugging build errors, please see the section in:
            http://wiki.documentfoundation.org/Development

  internal build errors:

ERROR: error 512 occurred while making
/fastdocs/programmer/libreoffice/libo/tail_build/prj

 it seems that the error is inside 'tail_build', please re-run build
