This is probably something you will have to debug yourself, since it
is dependent on the TK you have installed on your system, but it is
fairly easy to do. Edit setupext.py, store the results of
tmp = tk_vars.get("default", "TK_LIB_SPEC")[1:-1].split()
print tmp
and see what is returned. The setup code is trying to index into
this data structure, and what is coming back is not what is expected.
It would be helpful to see what is coming back.
Note this call happens in a large try except block, so you could add
your exception (IndexError) to the list of exceptions that are caught,
which will return None from this function. This will keep your build
from crashing. Alternatively, if you know you want some backend like
gtkagg or wxagg and don't need tkagg, you can turn this off by copying
setup.cfg.template to setup.cfg and manually customizing the backends
which are built.
But the ideal will be to fix the tk config bug and send us a patch .
