Configure: error: *** termcap support not found

I am new in Asterisk and Linux too. I am using Linux Distribution “UBUNTU 8.x “ (linux kernel ver 2.6 )
When I try to configure the Asterisk (ver 1.6)
Following error is encountered
configure: error: *** termcap support not found

now please tell me where to download and how to install “libtermcap-develâ€

apt-get install libtermcap-devel

when i use sudo apt-get install libtermcap-devel
error showing:
Couldn’t find package libtermcap-devel
i think there will be some different name for this package.

thanks for your reply.

using command
apt-get install libncurses5-dev the problem has been fixed.
