Bug#866508: sagemath: sage fail at starting with: ImportError: No module named 'sage'

[Tobias Hansen]

Just for the record, here [1] someone reported a similar problem. It was caused by a non-standard path (from an anaconda installation) prepended to $PATH. It was fixed by moving that path to the end end of $PATH.

Best,
Tobias
