Errors upgrading to 0.3 from 0.2 stable

[jlbrown]

When I run ./bin/update.sh I get these errors:
 
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
 
Any ideas what is causing this or how to fix it?
 
Thanks,
 
James.
