swi-prolog synaptic error

[akoskm]

Hi!
I'm trying to install the swi-prolog package from synaptic package manager, but it gives me an error after marking it for installation - and accepting the list off additional packages.


swi-prolog:
Depends: libgmp3-dev but it is not going to be installed
Depends: libreadline5-dev but it is not going to be installed
.
What is the problem?
Any ideas? Thank you.

After some searching I've figured out that the swi-prolog have unsatisfied dependency with the package:

1. libncurses5-dev
2. libncurses5-dev with libncurses5
3. libncurses5 with 1.

The point is that booth packages are contained in Synaptic so why??
After searching the Ubuntu package repositories I found the same package here:
http://packages.ubuntu.com/karmic/i386/libncurses5-dev/download
...so I've added:
deb http://cz.archive.ubuntu.com/ubuntu karmic main
to the sources.list and now everything installs fine.
