===> Installing dependencies for py38-scikit-learn-0.22.1nb1
==========================================================================
The following variables will affect the build process of this package,
py38-scikit-learn-0.22.1nb1.  Their current value is shown below:

        * PKGSRC_BLAS_TYPES = netlib openblas openblas_pthread openblas_openmp
        * PYTHON_VERSION_DEFAULT = 38

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

        * BLAS_LIBS = -lblas
        * BLAS_TYPE = netlib
        * LAPACK_LIBS = -llapack -lblas
        * PYPACKAGE = python38

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