SMF Mod Installation problem


I have installed the mod, but it won’t work since it requires fsockopen php function to be enabled. They however have said:

[quote]We’ve purposely disabled URL access to php system functions (such as
copy() open() fsockopen() etc.) because of security and performance
problems. We
have replaced it with CURL:

I have no knowledge of how to use CURL, if someone can help me with installing the above mod mentioned into my forums:
it would be greatly appreciated.
