- allow redistribution in source and binary forms with or without 
  modification

- copies must include the copyright/permission notice, optionally list of 
  conditions, and optionally the disclaimer

- optionally may mention about name not being used for 
  endorsement/promotion without permission

- optionally may have advertising clause: advertising mentioning the 
  software must display acknowledgement

- must not add other limitations (like "fees")

We can't have multiple licenses defined for each BSD-like for pkgsrc. I 
have found over 100 different worded licenses just in our manual section 
8 (see my netbsd-docs email 
http://mail-index.netbsd.org/netbsd-docs/2009/04/26/msg000096.html ).
