Issues installing slycot via pip #74
Description
Hello,
Currently trying to install slycot in conjunction with control.
No issues installing the control library in both Python2 and Python3.
While running sudo pip[3] install slycot, I get the following output:
Collecting slycot

I'd really like to know if this is a local issue and how to resolve it because I'm having issues using the main controls library because of errors related to needing slycot:
/usr/local/lib/python3.5/dist-packages/control/statefbk.py in lqr(*args, **keywords)
313 from slycot import sb02mt
314 except ImportError:
--> 315 raise ControlSlycot("can't find slycot module 'sb02md' or 'sb02nt'")
316
317 #
ControlSlycot: can't find slycot module 'sb02md' or 'sb02nt'
Thanks!
