configuration script can not find libcurl4-gnutls-dev

[Zisis Sialveras]

Configuration script can not find libcurl4-gnutls-dev package, although it is installed in my system. My OS is Ubuntu 11.10 using Linux Kernel 3.0.0-15-generic.
I made two attempts to install libcurl4-gnutls-dev . The first attempt was to install libcurl4-gnutls-dev following the "Installing build dependencies" instructions in the drizzle website. The second was from the synaptic pkg manager of Ubuntu.

There is the output from my terminal:
