            Bug ID: 242672
           Summary: science/py-scikit-learn (py36-scikit-learn-0.20.3_1)
                    fails due to unresolved symbols
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)

This issue was reported for the Python 2.7 flavor of this port a while back
here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194683

I get the following traceback:
  File "scripts/svm.py", line 13, in <module>
    from sklearn.svm import SVC
  File "/usr/local/lib/python3.6/site-packages/sklearn/svm/__init__.py", line
13, in <module>
    from .classes import SVC, NuSVC, SVR, NuSVR, OneClassSVM, LinearSVC, \
  File "/usr/local/lib/python3.6/site-packages/sklearn/svm/classes.py", line 4,
in <module>
    from .base import _fit_liblinear, BaseSVC, BaseLibSVM
  File "/usr/local/lib/python3.6/site-packages/sklearn/svm/base.py", line 8, in
<module>
    from . import libsvm, liblinear
ImportError: /usr/local/lib/libcblas.so.2: Undefined symbol "cgemv_"

Not sure whether it's worth addressing, though, since apparently a new version
of science/py-scikit-learn is on its way here:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=238718

If there is no interest in maintaining scikit-learn, I can claim maintainership
of the science/py-scikit-learn port beginning of next year since I actually do
use scikit-learn for my projects. In a separate report, of course.
