Mac OS X installer for MapServer.
Mapserv CGI, PHP-MapScript and Python MapScript are included. PHP-MapScript is for PHP CGI-only for now. Of course, PHP-MapScript needs PHP, but the CGI mapserv will run without PHP. Python MapScript uses the system Python, but it can also be installed for the python.org Python (v2.5 on Leopard and v2.6 on Snow). MapServer requires the UnixImageIO, FreeType, cairo, GEOS 3, PROJ and GDAL 1.6 frameworks. (note the new cairo requirement as of MapServer 5.6)
Note: I dropped FastCGI support because it doesn't coexist nicely with Python-MapScript. And recents discussions on the mailing list point out that there is only a tiny performance gain.
For help with MapServer, look at the documentation and mailing list on the MapServer website.
Included also are simple (and a bit old) drag-n-drop GUIs for the shptree, tile4ms and sortshp tools. The other tools you will have to use from the terminal.
For an up-to-date MapServer that runs on Panther or Tiger, see the build instructions to compile from source, or use the build script above.
