Another likely theory is that the message is not trying to complain
about plpython2.dll, but about some library that that depends on,
probably libpython itself. If you look into the postmaster log file,
rather than just at what's reported to the client, you might find
some additional low-level messages clarifying this.
If this were a Linux machine I'd recommend using "ldd" to investigate
the dependencies of plpython2.dll. But I don't know what the equivalent
tool for Windows is.
