Error code 9 - building with jmvc 3.3

Hi guys,

After few weeks without building our app I'm in front of a cornelian dilemma !

  app/webroot/js$ ./js ./steal/buildjs ./app/pb.html

Building to ./app/
  opening ./app/pb.html
code
!!!!!!!!!!! ERROR !!!!!!!!!!!

-code = 9

I solved all the classic small glitches the builder found, but this one makes me perplex !
The code base didn't change so much.

I would be thanks full if someone has an idea.

Cheers,
Ced
