--------------------------------+-------------------------------------------
 I added a new variant to my local php5 Portfile for db4 support so that I
 could use db4 via dba extension in php.  I would like to contribute my
 changes back to macports.  Can someone please review my changes and let me
 know if you find any issues?

 Thanks very much,

 Tin
