[JdeRobot] Error running Follow_line

  Hi again,

  finally* this problem was solved*! I am going to try to explain the
process I have followed:
  - I saw a "generateGUI" and I thought that I could not to have a gui
generated, so I tried to execute it. I got these errors:
./generateGUI: línea 3: pyuic4: orden no encontrada
./generateGUI: línea 5: pyrcc4: orden no encontrada
mv: no se puede efectuar `stat' sobre «resources_rc.py»: No existe el
archivo o el directorio
  - I "googled" such an error and I found I needed to run: "sudo apt-get
install pyqt4-dev-tools qt4-designer" in order to get such a dev tool.
  - Now I could generate my GUI, but the "follow_line" executable didn't
work yet.
  - I focused on the last message: "ImportError: cannot import name
resources_rc" which came from "[...]/gui/widgets/teleopWidget.py".
  - I went to that path and, yes, I didn't see any "resources_rc" nor even
in "[...]/gui/widgets/resources", where I could find a "resources.qrc".
  - I deduced I needed to get a "resources_rc.py" to satisfy the
"teleopWidged.py" which was searching it there.
  - So I ran: "pyrcc4 resources.qrc -o resources_rc.py" and voilà, I got a
"resources_rc.py" and my "follow_line" worked so fine.

  I am very happy but anyway I suppose something is wrong. I figure out I
shouldn't have done such a hard process.

  Thanks all for your help,

  Julio
