Thank you for your answer.
I did export the LD_LIBRARY_PATH and now the complain is something else..
progress :)
Error: Unable to initialize gtk, is DISPLAY set properly?
I have also launched the TuningWizard from an icon and I got to the step
(development, mixed, dedicated) as before and then the same message
(connecting to webserver) and then it disappears.
Thanks / Jen
