Oh and you could manually visit http://repository.maemo.org/extras/pool/fremantle/free/ and download the package and install via dpkg -i or use http://maemo.org/packages/view/mirror/ and choose the package from which repo you want and use dpkg to install it. Note: dpkg won't pull in any dependencies that it may need.

Embrace CLI.

P.S. You can lock a package to a specific version if so wish.

Do what fatalsaint said. I wasn't aware that debian-based package managers supported such a thing. I thought portage was the only one that had that "trick". Learn something new everyday.
