            Bug ID: 25744
           Summary: Linux build breaks when both python 2 and python 3 are
                    installed
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P

I'm not sure if this is new, but when both Python 2 and 3 are installed on
Linux, the readline overload module has code that is not Python-3 compatible. 
(I'm pretty sure I've run python 2/3 systems in the past and not hit this, so
it might have crept in more recently).

I think we want to limit Linux to Python 2.x in the short term.  Later, we can
iron out the Python 3 bits.  An alternative would be to fix up the basic
wrapper code to work on both Python 2 and 3, but that's a bit more involved.  I
prefer to handle that as a lower priority follow up step.

See initial report here:
https://bugs.swift.org/browse/SR-14

I'm still working on getting the exact repro environment, but calling it out
now.
