this should be http://chameleon.mydomain.com/ ... very poorly described,
will be fixed for release.

if it is not finding this then there is a problem with your php
configuration. To resolve this, first create a script called
phpinfo.php somewhere web accessible ...
<?php
phpinfo();
?>
and then access it by web browser, you should get the php info output,
if you don't then there is a problem you will have to fix ...
If it does work then in the top block it will tell you which php.ini
file it is using (perhaps, depending on how you configured php when you
built it). You need to look in this file to see where your
extension_dir is pointing to and make sure that php_mapscript.so is in
there. You will also need to make sure that the run time linker can
find dependencies (run ldd php_mapscript.so)
If that appears correct, then change the script to:
<?php
dl( 'php_mapscript.so' );
phpinfo();
?>
and open it again, this time you should get a MapScript block somewhere
in the output. Once that is working, try chameleon again.
If chameleon is still not working, check the location of
session.save_path in php.ini and make sure that it is writable by the
web server's user.
If all of that is okay without changes, get back to me again :)
