Not saying Python's any better. Though how do you make a Python program work on 3.x but not 3.x+1? I thought they had ended backward-incompatibility with the 2 to 3 update? My experience with C/C+=/Fortran problems is not just versions of dependencies but version of compilers, platforms (they're non very portable), and mostly the extreme unhelpfulness of the error messages. It's always some undefined symbol that seems like it should be fine but turns out you're supposed to use all sorts of special command line parameters on the compiler and linker to make it work just right.
