scipy error Undefined PLT symbol "chla_transtype_"

[Mayuresh <mayuresh%acm.org@localhost>]

On NetBSD 8.0 with pkgsrc current on amd64, I get this:

Python 3.7.7 (default, Apr  6 2020, 17:14:24) 
[GCC 5.5.0] on netbsd8
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy.linalg
Traceback (most recent call last):

    from ._decomp_update import *
  File "_decomp_update.pyx", line 1, in init scipy.linalg._decomp_update
ImportError:
/usr/pkg/lib/python3.7/site-packages/scipy/linalg/cython_lapack.so:
Undefined PLT symbol "chla_transtype_" (symnum = 685)
>>> 

Any hints to try?
