Note that
/scp:dev-dsk-sdsg-1e-cfbb346a.us-east-1.amazon.com:/workplace/sdsg/lpt/src/A9IFSDataScience/back-testing
exists and is my remote working directory on Linux.

However, Contents/Resources/site-lisp is a local(macos-specific)
directory, and "nntp.so" is probably a hypothetical natively compiled nntp.el.
Basically, a local and a remote paths are combined in search of a file
that does not exist either locally or remotely.
