[QScintilla] Problem installing QScintilla2:fatal error: QAbstractScrollArea: No such file or directory

[Thies Thate]

I'm hobbyist trying to program in PYQT5.
Working on a Lenovo ThinkStation E32 (64bit) under Fedora 21 Mate.

To install eric6 I did the following:
As explained in "README for the eric6 IDE" (in eric6-6.0.1.tar.gz from
http://sourceforge.net/projects/eric-ide/files/eric6/stable/

1.Install Qt5 Qt Creator 3.3.0 Based on Qt 5.4.0 (GCC 4.9.2 20141101 
(Red Hat 4.9.2-1), 64 bit)
2.Build and install QScintilla2 (from Riverbank Computing)  (my remark: 
I had to put  qmake in PATH for missing qmake)
3.Build and install sip (from Riverbank Computing) (my remark: I had to 
install python3-devel for missing python.h)
4.Build and install PyQt5 (my remark: no problems)

And now my problem:

Firstly the contents of .bash_profile:

============================
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
     . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

#tbv qmake thies 26-01-2015

PATH=$PATH:/usr/lib64/qt5/bin
PATH=$PATH:/usr/include/qt5/QtWidgets

export PATH

==================


5.Build and install QScintilla2 Python bindings.
Next the output in terminal:

===============================

My problem described above: "QAbstractScrollArea: No such file or directory"

I'm missing QAbstractScrollArea.
A "find" as root gives the following:

I found qabstarctscrollarea.h in 
/usr/include/qt5/QtWidgets/qabstractscrollarea.h
So I put that directory in .bash_profile without the needed solution. 
(not knowing what to do!!)

(Because I also have qt4 installed (for hplip-gui) I thought the problem 
is the existence of
Qt4. But uninstalling this does not have the needed effect.

Question can you help me to solve this problem?

Many thanks.
