So? The Linux ecosystem is the best there is for science. Period. Even OSX lags behind, just look at all the work people put into MacPorts and Homebrew just to get it almost on par with Linux. To this day, none of those systems properly handle the case of multiple packages providing implementations of a library that other packages depend on (e.g. OpenMPI vs. MPICH). Not to talk down on the guys working on that, they are very talented, and the amount of effort they put in is of huge value to the community. (Hello Sean, hello Geoff.)
