Package: pyhoca-gui Version: 5.0.0.0-preview I followed the pyhoca-gui build instructions simultaneously on both the X2Go-WinBuilder VM, and my home desktop (excutor.) The former is Windows 7 64-bit SP1, the latter is WIndows 8.1 64-bit with update 1. They both get the same error. I also tried building under both Msysgit bash and under cmd.exe Instructions (it's the very last step that fails.) http://wiki.x2go.org/doku.php/wiki:development:build-howto-mswin:pyhoca-gui setup common to both machines: Python 2.7.8 32-bit (Released 3 days a go) bbfreeze-1.1.3-py2.7.egg bbfreeze_loader-1.1.0-py2.7-win32.egg py2exe-0.6.9.win32-py2.7 Msysgit (AKA "Git for Windows") 1.9.4-preview20140611 (In other words, I have both bbfreeze and py2exe installed.) I've attached the output because I do not want its 80+ character long lines to be split up.
