    gr-utils: Update error message
    
    Prevent people from running into the problem that "import pylab" doesn't 
work because python tkinter is not installed.
    For example on a fresh Ubuntu or Mint system it is not enough to install 
python-matplotlib.
    However, the true error message:
    "ImportError: No module named _tkinter, please install the python-tk 
package"
    is obfuscated towards the user.
    
    Another good option would be to not catch this import error but just show 
the true error message from python to the user.
