Finally finished updating the Mapserver, PHP, Postgres and libraries installers for Tiger. The old ones still work on Tiger, it's just official now. Cleaned things up a bit also. The only version change is to Postgres 8.0.3 and PostGIS 1.0.1. And MrSID has been dropped from GIS Libs (a Tiger issue).
All installer now do version and dependency checking. No worries about forgetting something. Minimum requirements have been upped to Mac OS 10.3.9, Mac OS 10.3.6 compatibility would have required much more work but the old installers are still available. But, Postgres is not required for GIS Libs, PHP and MapServer if you don't need it. Install just what you need!
Now to work on the build instructions.
