Any idea why pillow / PIL wouldn't be included in a PEX despite declaring a module_mapping of

"pillow": ["PIL"]

(like I had to with

"setuptools": ["pkg_resources"]

for runtime needs) and even explicitly declaring a file's dependency on it?

Sorry for the trouble. Any warnings? Can you create a reduced reproducer?

Sorry mobile atm - no evident warnings; I’ve reset the pants environment from scratch but no luck. Going to try to publish a minimal repro once home
