Ubuntu – cURL Libraries on Ubuntu 9.10 Server Running SugarCRM Causing Problems with Scheduler

Running Ubuntu 9.10, Apache 2.2, MySQL 5.1.37, PHP 5.2.10, SugarCRM Pro 5.5.4

I started out by trying to use a Sugar function call Scheduler and Sugar complained:

This system does not have the cURL libraries enabled/compiled into the PHP module (--with-curl=/path/to/curl_library). Please contact your administrator to resolve this issue. ``Without the cURL functionality, the Scheduler cannot thread its jobs.

I confirmed curl, libcurl packages are installed on the system.

But now I am having trouble finding out what file to point to in the php.ini file. Some forums say I need a php_curl.so file (similar to the php_curl.dll in Windows) but I can only find curl.so. Where do I change the extension_dir=/path/to/libraries to point to?

Since I don't have a php_curl.so file, should I make the extension= to curl.so?

Some output when I restarted my apache2 is here:

PHP Warning: PHP Startup: Unable to load dynamic library './php_curl.so' - ./php_curl.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library './curl.so' - ./curl.so: cannot open shared object file: No such file or directory in Unknown on line 0

Any help is greatly appreciated!
