 Some parts of the harness assume a clean **Mercurial** clone of the mozilla trees. There is insufficient testing with Git for now - please file an issue if you hit problems with Git repositories of mozilla trees.

   * Fedora: (Fedora is known to work, however the exact library names are unknown for now.)
-  ** Note that parts of the code which contain ```if isLinux and float(platform.linux_distribution()[1]) > 15.04``` might fail on Fedora, as they assume Ubuntu's versioning scheme. Patches welcome.
 3. Install gdb:
   * Debian/Ubuntu: ```sudo apt-get install gdb```
   * Fedora: Please ensure that all development packages are installed (see ```rpm -qa "*devel"```), and run ```yum install gdb```
 4. Install clang for clang/ASan builds:
