Comment:
May I suggest that we split off a package like
```
sagemath-devel_package() { # or whatever you want to call it
 depends = "sagemath"
 depends += "move here all the -devel that is in sagemath depends, the compilers etc"
 desc += "development stuff, needed to pass all doctests, compile cython code etc."
```
Do you see any drawbacks?
