problem with wxPython3.0.2 installation on MAcOS , virtualenv

Hi to everybody,

I having such a bad time in trying to install wxPython on my mac (MacOS sierra) .

My goal was to install the version 3.0.2 for the python-mapper , all wrapped into my virtulenv.

I downloaded the sources directly from sourceforge, downloaded wxWidgets withbrew (brew install wxwidgets) , launched the command “python2.7 build-wxpython.py build_dir=–/bld” as suggested in the README, but this error goes on popping up in front of my eyes:

File “build-wxpython.py”, line 389, in

wxbuild.main(wxscript, build_options)

File “/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/build/tools/build-wxwidgets.py”, line 485, in main

exitIfError(wxBuilder.build(dir=buildDir, options=args), “Error building”)

File “/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/build/tools/build-wxwidgets.py”, line 80, in exitIfError

raise builder.BuildError(msg)

What am I doing wrong? Or missing?

thank you very much
