SDO_DAS ext for Zend Studio

[locolocal]

>>USING: Server2003 SP2, Apache 2.2.13, Zend Core 2.5.2, PHP ver 5.2.6 <<

I've followed the directions in the PHP manual in installing the SDO module for windows. Something like: put the DLL in the extensions folder; allow the extension in php.ini; and add the pear classes (pecl install SDO_DAS). While trying to do the PECL install I get an error --

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\Program Files\Zend
\Core\lib\phpext\php_sdo.dll' - The specified module could not be found.
in Unknown on line 0

It's there and it's supposedly php_sdo.dll version 5.2.7.7 .

When I try to use it in a script, of course it fails.

Any ideas???
