It is readline that needs termcap. That it is not automatically included must
mean that the readline lib is not properly installed.

bash-2.04$ ldd /usr/lib/libreadline.so 
        libncurses.so.5 => /lib/libncurses.so.5 (0x40030000)
        libc.so.6 => /lib/libc.so.6 (0x4006e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

At least I hope it is not our responsibility to include readlines dependensies,
cause they vary with OS and readline version. It wouldn't be logical.

This should be added to various FAQs.
