QtMoko v31 broken build?

[Marco]

Hello everyone,
 although someone already mentioned this problem, I couldn't find a solution to
it. I build QtMoko from git sources following the guide on the wiki, but when it
comes to running it (./runqtopia) I get this error:

Use of uninitialized value $word in concatenation (.) or string at 
bin/../src/build/bin/Qtopia/Opt.pm line 551.
ERROR: Invalid value for option "skin": 
       Valid values: 
The default value for skin is invalid! at bin/../src/build/bin/Qtopia/Opt.pm 
line 252.

I tried to move the skin packages in different folders (after looking at the
launching script) but with no results?

What could I have done wrong to get this errors? Any suggestion on how to fix?

As always, many thanks in advance to everyone!
