Comment:
> Let me first say you've done a great job. I'm building it right now, will report soon. My only comment is about `depends`: is there a way not to bring in `-devel` and `gcc-` stuff?

I only added stuff that is needed to pass doctests. There is some functionality to cython-compile code (e.g. you may want to define a function in cython inside a notebook) and that needs at least headers and sometimes libraries, and a working gcc (which is required indirectly via gcc-fortran).

It might be possible to add "features" to sage that correspond to presence of gcc and headers, etc. but I'm not sure this is worth the trouble. Although some sage developers are trying to move it in a "modularization" direction such that it's possible to split it in parts and in that sense it could make sense to split out a "sagemath-cython" subpkg that gives this ability, etc.
