Missing or unbuildable dependency chain...

El3ctroded
I got this error when doing bitbake lcdslider, where lcdslider is an
example qt4 app from
http://www.developmentboard.net/index.php/article/Creating+Qt4+project+w...

Missing or Unbuildable dependency chain was: ['qt4-embedded-gles',
'virtural/egl']

What does this mean? What do I do about it?

Thanks!
