[vtkusers] changes from 4.x to 5.x

[Mathieu Malaterre]

Sorry I have never that issue before :(

I would use 'python -v' to make sure that the new libraries are
actually the one used by python (and not the old ones).

the only reason why the compilation would stop while return no error
(echo $?), is that you have aliased make to 'make -i'
