cerbero must be run in the MingGW shell, which is accessible from the main menu.
The last step is making python and git available from the shell, for which you will need
to create a .profile file:
  $ echo "export PATH=\"\$PATH:/c/Python27:/c/Git/bin\"" > ~/.profile

Note that inside the shell, / is mapped to c:\Mingw\msys\1.0\

should IMHO be explained as:

cerbero must be run in the MingGW shell, which is accessible from the desktop/main menu as "MinGW Shell" (if you don't have it, you did not install the bash lnk" package).

Once you run the shell, you need to make python, MinGW and git available from the shell, for which you will need to create a .profile file:

If you use 64-bit Windows:

echo 'export PATH="$PATH:/c/Python27:/c/Program Files (x86)/Git/bin:/c/MinGW/bin/"' >  ~/.profile

if you use 32-bit Windows:

echo 'export PATH="$PATH:/c/Python27:/c/Program Files/Git/bin:/c/MinGW/bin/"' >  ~/.profile

Note that inside the shell, / is mapped to c:\Mingw\msys\1.0\

There are two issues fixed besides more explanation:

- Git is now installed in Program Files, not in c:\git; and
- msys shell for some unknown reason does not have mingw in path, so once you start cerbero it couldn't find mingw-get and fails.
