* gr-utils: Update error messageiohannez2016-01-171-1/+1
| | | | | | | | | | 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.
