Maple optional tests

[SimonKing]

I was running the doc tests of sage.interfaces.maple on bsd.math, using sage-4.7. Result:

sage -t -long --optional sage/interfaces/maple.py
Detected SAGE64 flag

The following tests failed:


        sage -t -long --optional "devel/sage-main/sage/interfaces/maple.py"
Total time for all tests: 11.2 seconds

I have no idea whether the errors are the same on other machines.
