Curl Function problem

Hi, Having issue to install the Curl() function on Asterisk 11 running on Ubuntu Server 12.

I installed the dependency $ sudo apt-get install libcurl4-openssl-dev

i verified that on the asterisk installation on the make menuselect, menu the curl function is selected but it does not work on my dial plan.

[Jan 29 01:00:27] WARNING[13333][C-00000010]: pbx.c:4621 pbx_extension_helper: No application ‘CURL’ for extension (extensiones, *764, 3)
