Submitted By: DJ Lucas <dj_AT_linuxfromscratch_DOT_org>
Date: 2004-12-24
Initial Package Version: 1.1rc4
Origin: openoffice-1.1.2-no_pam-1.patch (Tushar Teredesai)
Description: OpenOffice requires PAM headers in /usr/include/security; 
  these headers are not available in most of the LFS based systems. This 
  patch removes the need for PAM headers by removing the functions that 
  use PAM.  Updated for OpenOffice-1.1.3
Upstream Status:  Not Required
