Comment (by mkoeppe):
I get this (on Mac OS X):
{{{
File "src/sage/numerical/mip.pyx", line 2477, in
sage.numerical.mip.MixedIntegerLinearProgram.number_of_variables.get_backend
Failed example:
p.solve() # rel tol 1e-5
Expected:
GLPK Simplex Optimizer, v4.60
2 rows, 2 columns, 4 non-zeros
* 0: obj = 7.000000000e+00 infeas = 0.000e+00 (0)

OPTIMAL LP SOLUTION FOUND

Got:

Should this ticket be in `needs_review`?)
