I am sure someone else will correct me if I am wrong, but you
need the Cygwin versions of these, not the Windows or Linux
versions.  I suspect PIP does not fetch Cygwin versions, thus
you must acquire these via setup.  However, they are not
required for base python, so you have to request them explicitly
in setup ...

An alternative is to build them from source yourself under Cygwin,
which I seem to recall doing at some point ...
