Hey Michael, Hey Kevin, Hey all,
thanks for your help!
I found that by specifying the python version I want to use when running the
file, everything works fine. Like this:
python2.7 if_else_mod.py
This would be acceptable for me, however, I decided to do some of the stuff you
suggested. I get the following output when running env:
Patricks-iMac:~ patrick$ env
TERM_PROGRAM=Apple_Terminal
SHELL=/bin/bash
TERM=xterm-256color
TMPDIR=/var/folders/3j/qy7_9bpx29g_nf_ymbkw_td00000gn/T/

_=/usr/bin/env
I see that I only have a PATH variable set, but no PYTHONPATH. And
/opt/local/bin seems to be the first in place?! With
Patricks-iMac:bin patrick$ pwd
/usr/bin
Patricks-iMac:bin patrick$ ./py
pydoc python python2.6-config pythonw
pydoc2.6 python-config python2.7 pythonw2.6
pydoc2.7 python2.6 python2.7-config pythonw2.7
I see that I have even more python installs. Now I ran
Patricks-iMac:bin patrick$ which python
/usr/bin/python
Patricks-iMac:bin patrick$ port select --list python
Available versions for python:
none (active)
python26-apple
python27
python27-apple
So terminal normally would run "python" (didn’t look up the version). And
MacPorts?
All this is what comes out of a clean OS X 10.9 install with an update to 10.10
and then a GNURadio install via MacPorts. Didn’t try yet to change one of the
env variables or use the 'sudo port select python python27‘ command. What would
your suggestions now be? What I don’t understand is why I have to tell MacPorts
to use python2.7, if in fact I want to tell that to my terminal?
Thanks & Regards
Patrick
