HI Rodrigo, I don't what settings your used, or the hardware/drivers you are using so can't pinpoint what the problem might be. If you run osgscreencapture with --pbuffer-only you get the warning:
$ osgscreencapture cow.osg --pbuffer-only osgscreencapture: argument to `--pbuffer-only` is missing osgscreencapture: unrecognized option --pbuffer-only If passing the dimensions of the pbuffer that I want then the context is created correctly and I get: $ osgscreencapture cow.osg --pbuffer-only 800 600 Pixel buffer has been created successfully.

Pbuffer still use GLX so you'll need X11 to be able to create a Pbuffer, you just won't need an actual window. Am I reading you correctly that you are trying to run without any X server running? If so then you'll need to create your GL context yourself another method if one is supported by your drivers.
