[Eric] problem running eric4

[Vincent Schut]

Hi,

I'm trying to get eric4 up and running. I have installed Qt-4.2.0, the 
latest sip snapshot, the latest PyQt4 snapshot, the latest QScintilla 
snapshot, and the latest eric4 snapshot.
Everything compiled and installed OK.

However, when trying to launch eric4, I get the following error:

Warning: translation file 'qt_en_US'could not be loaded.
Using default.
Warning: translation file 'eric4_en_US'could not be loaded.
Using default.
Warning: translation file 'qscintilla_en_US'could not be loaded.
Using default.

TypeError: argument 1 of QsciScintilla() has an invalid type

Can someone give me a hint what I've done wrong?

Cheers,
Vincent.
