[X2Go-Dev] Bug#534: Windows: PyHoca-GUI fails to start (ImportError: No module named wx)

[Michael DePaulo]

package: pyhoca-gui
version: 0.5.0.0-preview

For some reason I cannot figure out, on my home desktop (Windows 8.1
with update 1 64-bit) I experience the error below when I try to
launch PyHoca-GUI in development mode.

I have not been able to testPyHoca-GUI in regular/installed mode due to #531.

Yet on the X2Go-WinBuilder VM (Windows 7 64-bit SP1,) which I am
almost certain I did the same exact setup work on (according to the
instructions immediately below), it does not have the problem. It
launches pyhoca-gui successfully.

I've attached a 1 line fix. I'd like to discuss it before I commit it.
