http://downloads-distro.mongodb.org/repo/ubuntu-upstart does not contain -devel package for mongodb distro (mongodb-10gen does not contain headers and libraries too).
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ does not describe where to get -devel package.
It's very uncomfortable, install latest stable version and do not have header and libs to link my C++ application with.

Launchpad has no latest stable mongodb too. So I am in trouble on Ubuntu platform to compile C++ mongodb application. Building mongodb every time new stable version releases not best solution for avarage server (due to its does not requre hi perfomance tunings).
