This is very hard to troubleshoot at the moment, because I just can't get the build-dependencies installed, either with noble or noble-proposed: noble: $ sudo apt-get build-dep . Note, using directory '.' to get the build dependencies Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.
