Aha, I think this is the issue we are hitting:

https://github.com/podofo/podofo/issues/27

It was fixed in podofo git back in October, and should be in podofo 1.0
(but their latest release still seems to be 0.10.4).

Looks like it might work if we ship OpenSSL's legacy.dll (which seems to
get loaded at runtime so would have been missed by walking the DLL
dependency tree).  I can try that.
