According to pytave's dev,
That makes sense. We've had problems like this before. E.g., at one point suddenly MatPlotLib had a new C++ type with the same name as something in another C++ library that Sage links in (maybe licecm or NTL). The fix that time was to change libecm or NTL. William > "The problem is conflicting implementations of Array<int>.
