it is also ipython 5.0, which, as we know, is problematic.

But -- perhaps surprisingly, the error /here/ is unrelated to IPython.

I guess it's Sage 7.4.beta0 though.

I cannot help if you don't write the message error and if you have not 
given points16-txt file content.

After copying your code in sageworksheet cell and running cell, I have only 
the error

IOError: [Errno 2] No such file or directory: 'points-16.txt'


Post too your computer environment : are you using sagemath cloud ?

Your code has no syntax error, and what you name "error" could be either a 
math/graph mistake or a algorithm coding one. 

Printing intermediate variables like x,y or I is strongly recommended 
(insert "print  " lines) : you might be surprised by some results (for 
example : symbolic values where you guessed float values).

Dominique.

Don't think so, as libgsl.so must have been there during link of the
extension module.

Either ldconfig has messed up the links, or probably some RUN_PATH issue.

(Or he really took some [incomplete] binary built elsewhere.)
