that has nothing to do with it.
the error means it cannot use the cURL function because it is not enabled.
create a new PHP file and add the following code to it:
<?php phpinfo(); ?>
this will write a bunch of information regarding the php server to the screen.
If curl is enabled you should see a section titled cURL with entries similar to this:
cURL support enabled
cURL Information libcurl/7.19.5 OpenSSL/0.9.7l zlib/1.2.3 libidn/1.15
if you dont see that information in the phpinfo page, then cURL is not enabled.
