Packages on your system need not always be used by conda, sometmes
conda installs its
own packages (e.g. this is often the case with compilers).
Cf. 
https://doc.sagemath.org/html/en/installation/source.html#notes-on-using-anaconda-miniconda

One way to make sure that all the conda packages needed to build Sage
are installed is to install
conda's Sage.
