I fixed this, but conda still has errors; it tries to write to the
store:

Wherever it says “/gnu/store/yd655bpcqrzch4ai1dhs7v39yhm70mdi-python-3.5.3/” we 
should provide sane
defaults.

@Fred: could you please look into this?  This may require patching the
conda sources.

I’m marking this bug done now, because Conda is now in the repository.
