Kivy does not provide a python shell on yosemite - osx-yosemite

Question

I failed to let kivy work on my mac (yosemite 10.10.4). After placing kivy in applications and running makesymlinks, I expected to get a python shell after the 'kivy' command. However, I got the following error.
Script started, output file is started
Script: on: No such file or directory
Script done, output file is started
/usr/local/bin/kivy: line 2: bash-3.2$: command not found
/usr/local/bin/kivy: line 3: bash:: command not found
/usr/local/bin/kivy: line 4: bash-3.2$: command not found
: command not found: line 5: Password:
/usr/local/bin/kivy: line 6: sudo:: command not found
/usr/local/bin/kivy: line 7: syntax error near unexpected token `('
'usr/local/bin/kivy: line 7: `bash-3.2$ exit()
Meanwhile I started developing on ubuntu, which works fine, but if I want to deploy my app on my ipad, it seems that I still need kivy nicely installed on my mac, because buildozer seems to require to run on mac when deploying for iOS.
Any tips are very welcome.
Note: I tried macport too, but received the following error
Error: org.macports.build for port py27-kivy returned: command execution failed
Please see the log file for port py27-kivy for details:

Answer 1

I ended up to conclude that the Kivy installation was corrupt. Re-installing it was not enough, but first uninstalling the existing one, and afterwards install a fresh download brought a solution.
I found this solution thanks to qua-non, who was also active in the kivy users support group. Thanks!
