Both the openoffice.org-3 and openoffice.org-3-RC ports have a problem with patch files containing MS-DOS EOR markers (extra ^M or CTL-M). openoffice-3 has this only in the patch file for "curl"; openoffice-3-RC has this with both "curl" and "neon".
The openoffice.org-3 pr is "ports/134305".
The fix is to start the build, then edit the two patch files ("./curl/curl-7.12.2.patch" and "./neon/neon.patch") and eliminate the extra "^M" characters. I used "vi" and ":1,$?^V^M??" ("?" followed by control-V and control-M and another two "?" characters). There is plenty of time to do this after the build starts, at least on a dual 2Ghz Xeon.
How-To-Repeat: Rebuild without patching
Over to maintainer.
