looking in /opt/gngeo-gui

i tried this:
a) gngeo-gui.py doesn't have the +x permission on it. applied it with chmod.
b) launching it from command line, i see a bunch of errors:
./gngeo-gui.py: line 1: import: not found
./gngeo-gui.py: line 2: import: not found
./gngeo-gui.py: line 3: from: not found
./gngeo-gui.py: line 4: from: not found
./gngeo-gui.py: line 6: COMMENT_CHAR: not found
./gngeo-gui.py: line 7: OPTION_CHAR: not found
./gngeo-gui.py: line 8: syntax error: unexpected "("
