Python package issues

[Sad Clouds <cryintothebluesky%gmail.com@localhost>]

Hi, I'm using pkgsrc-2019Q1 and I'm seeing some issues around python
package versions

===> Installing dependencies for py37-setuptools-40.8.0
==========================================================================
The following variables will affect the build process of this package,
py37-setuptools-40.8.0.  Their current value is shown below:

        * PYTHON_VERSION_DEFAULT = 27

Based on these variables, the following variables have been set:

        * PYPACKAGE = python37

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/bin/make clean' after
the changes.
==========================================================================

I don't have any python versions set in mk.conf

Any idea what is going on here?
