pkgsrc/security/cyrus-sasl/patches/patch-ae
jlam 4890f5ad3c Update cyrus-sasl to 1.5.24nb2: 
* Move headers to ${PREFIX}/include and get rid of need for the MD5
  headers.
* Move creation of cyrus user and mail group from cyrus-imapd to cyrus-sasl.
* Always compile support for pwcheck.
* Supply a ${PREFIX}/etc/rc.d/pwcheck script that drops in the rc.d startup
  scheme.
* Supply a sasl-config script that can return compiler flags needed for
  linking against -lsasl.
* Install documentation.
* Supply DEINSTALL/INSTALL scripts to manage the /var/pwcheck directory
  and /etc/sasldb shared secrets database.
* Improve the descriptions in the COMMENT and DESCR files.
* Make me the maintainer.
