update.sh error "unable to load dynamic library"

[jlbrown]

When I run:

sudo ./bin/update.sh I get:

PHP Warning:  Unknown(): Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20020429/php_gd2.dll' - (null) in Unknown on line 0
PHP Warning:  Unknown(): Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20020429/php_openssl.dll' - (null) in Unknown on line 0
PHP Warning:  Unknown(): Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20020429/php_sockets.dll' - (null) in Unknown on line 0

Fatal error: Call to undefined function: spl_autoload_register() in /Library/WebServer/Documents/roundcube/program/include/iniset.php on line 108

I'm upgrading to 0.3 stable.

Any hints as to how to fix this?

Mac OS X 10.5.8.

Thanks,

James.
