import fasttext_pybind as fasttext fails with undefined symbol

[HughPH]

This is with fasttext 0.9.2

(pile) hugh@gpuserver:/mnt/store2/the-pile$ python the_pile/pile.py --interleave_output 30 --using pile_repro
Traceback (most recent call last):

With any version prior to 0.9.0 (and after 0.5.x) I get a different error:

Traceback (most recent call last):

All code is entirely unchanged from this repo.
