Comment (by casey.webster@…):

 Replying to [comment:18 michaelld@…]:
 > NP. I've no idea why it would build for you & not others. It doesn't
 build for me because of the TBD libraries issue.

 Figured out it is building for me because my default python is 3.4.  Qt
 runs a python script that bails on a print without parenthesis causing a
 SyntaxError to be raised and fails to retrieve a python version number.
 It then assumes python < 2.7 and disables qtwebengine from being built.
 That explains why I am "successfully" building Qt while others are running
 into errors in Qtwebengine.

 Using Python version ., but at least Python version 2.7 is required to
 build Qt WebEngine.
 QtWebEngine will not be built.
