[PyQt] Qt 5.5.1 + PyQt5 configure .. Error: Unable to create the C++ code.

[dl]

I'm a newcomer to this forum.
I am starting to use Qt 5 for development on Ubuntu 14.04 (32bit).
I managed to get Qt 5.2.1 + PyQt working earlier and run some basic test
apps in Qt Creator.

While attempting to install latest eric6 IDE I encountered this ..
/"Sorry, you must have Qt version 4.8.0 or better or 5.3.0 or//better"./

So I decided to upgrade to Qt 5.5.1 and then install latest PyQt snapshot.
I purged all older Qt versions and now have Qt 5.5 Creator working as
before.

...

My current problem is getting Qt5.5.1 + latest PyQt5 working.

I have both python2 and python3 installed to choose from.

After running ... python3 configure.py ... I received this report.

Can you advise how to progress beyond the "unable to create the C++
code" error in configure?
i.e. to configure / make / install PyQt5 latest snapshot (with latest
SIP snapshot).

I have searched around and some other users have reported this Error.

Here is output from qtchooser ...

    qtchooser -print-env
    QT_SELECT="default"
    QTTOOLDIR="/opt/qt55/bin"
    QTLIBDIR="/opt/qt55/li"

I did notice that the value of QTLIBDIR is truncated and surely should
be  "/opt/qt55/li*b*".   Is this a clue?
