I was using a mac-ports based LAMP stack before upgrading to Mavericks from Mountain Lion and all was fine..
The file is ok (if you cat the file, the whole thing is readable)
Browser/cURL works fine with other hosts.
Tried OSX permissions check
Tried upgrading macports -> port selfupdate -> port uninstall all -> port clean all -> port install $everything and the behavior continues..
lsof reports that apache is reading all the correct library references to the mac ports versions..
