I want to fix this issue https://github.com/scipy/scipy/issues/7001

I made the fix, but i can't include it in scipy.

I changed eval_jacobi function in https://github.com/scipy/scipy/blob/master/scipy/special/orthogonal_eval.pxd 

and tried to reinstall scipy, but i don't get changes in eval_jacobi.

I  also tried to run generate_ufuncs.py once again and install again scipy, but i don't get fix in eval_jacobi.

What am i doing wrong?

Best regards,

Evgeny Zhurko.
