What you need is the libcurl library, not the program curl (which you
sudo apt-get install libcurl4
and probably (if not installed automatically by apt):
sudo apt-get install libcurl4-openssl-dev
Now it should work.
PS. you may always check which package provides a particular file by using:
apt-file find libcurl
