Unable to run php from Windows command line

[thea]

Trying to run any php script from the command line, I get the following error messages:

Failed loading \xampp\php\ext\php_xdebug-2.0.0rc1-5.1.2.dll
PHP Warning: PHP Startup: Unable to load dynamic library '\xampp\php\ext\php_gd2.dll' - The specified module could not be found.
...

It goes thru the list of all extensions enabled in php.ini and complains they cannot be loaded. I checked most of these extensions and verified they are located in "D:\xampp\php\ext\".

Any suggestions? Thanks.
