Package depends on python-support version >= 0.7.1, Ubuntu has version 0.6.4ubuntu1.
On the other hand, the tarball works perfectly on the same setup.
So why the dependency?

this is not a known but expected bug. The package was created for Ubuntu Hardy exclusively, mainly because it will now be an official part of Ubuntu. That was a big step and most of the last changes have been made for it. Many changes have been made regarding the deb packaging and now since it is part of Hardy it will be 'backported' to Gutsy and Feisty too. You might want to install the package with dependencies ignored.
dpkg --ignore-depends python-support -i *.deb
should do the trick. Python-support does not do very specific things since BlueProximity won't install external modules. I am sorry but I can't change things until the week after next week.
The package should be ready to install. I think this fixes this bug.
