Comment:
I am now getting, on two different machines, doctest failures in `mip.pyx`
when #12736 is applied. They report different lines (different betas,
different patches applied, I guess) but the basic idea is this:
{{{
Expected:
Traceback (most recent call last):
...
MIPSolverException: 'GLPK : Solution is undefined'
...
Got:
Traceback (most recent call last):
...
MIPSolverException: 'GLPK: An error occurred in the solver'
}}}

At first, I thought it was just a matter of the space, but then I realized
the errors were different, too. I'm going to look into this real quick.
Also, I added a dependency to the ticket description.
