Existing fix for py-scipy shared objects with incorrect @rpath/libmkl_rt.dylib?

[Steven Smith]

Re: https://trac.macports.org/ticket/62578

Is there a python or Portfile one-liner fix for the incorrect @rpath issues in py-scipy’s shared objects?

We can code up an exhaustive search of the build for all the .so's and use install_name_tool-correct to correct this, but if possible I’d like to use an existing, simpler approach.

Current issue:

$ python3 -c 'from scipy import special'

Traceback (most recent call last):
