The latest set of updates on Ubuntu installs GCC 4.4 and breaks the Boost library, which means Datamux won't compile. Initial Googling suggests that this issue has been around since 2008-ish, but no solution has been posted other than "use GCC 4.3". Current work-around is to use interactive mode when generating the project makefiles in Linux (cmake -i), show advanced settings, and enter "gcc-4.3" as the compiler. More research is needed to determine a permanent solution.
