Thanks for the tip, ArnimS.

I think I solved the problem by adding the repository...

Web address: http://repository.maemo.org
Distribution: mistral
Components: free non-free

...to my repo list. It was was (mysteriously?) not there. I only had the /extras repo, by default. *shrug*

Also, before figuring that out, I poached the bora version from...

http://repository.maemo.org/pool/bora/free/binary/

...and installed it manually. That seemed to work OK, too. Not sure there's any difference.

Yours,
