Can somebody help me with this error:

error: derivation '/nix/store/vpqdfii0wxr07lllar5lzyma87kah9rf-hdf5-1.14.3.drv' may not be deterministic: output '/nix/store/s6asby9qs04vfrn6fwyymaa706hhr6ry-hdf5-1.14.3' differs
``` ?

In reply to @zopieux:matrix.zopi.eu
call for help: nix-build -A tests.writers.simple.pypy2 fails because it invokes a py3 file with a py2 interpreter, but according to this bit it should use py2; so I suppose there some plumbing not working as it should?
