I don't know why but the Makefile was not created in 
.../PyQt-gpl-5.0-snapshot-cdc78cf84e0d/designer/

So, I've re-run the configure.py and the make and make install only for 
the designer.

Now the lib libpyqt5.so is in 
/usr/lib/Qt5.0.2/5.0.2/gcc_64/plugins/designer/ but the Designer crash 
at launching with any of my custom widgets and also with the 
geolocationwidget example provided here:
http://doc.qt.digia.com/qq/qq26-pyqtdesigner.html

I've tried all my widgets separately, this is the feedback of the command
------------------------------------------------------------------------
vincent at djoliba:~$ /usr/lib/Qt5.0.2/5.0.2/gcc_64/bin/designer
QMetaType::registerType: Binary compatibility break -- Size mismatch for 
type 'QPaintBufferCacheEntry' [1024]. Previously registered size 16, now 
registering size 0.
Abandon (core dumped)

Except for one widget wich I've had this backtrace:
