I don't use emacs but my guess would be that this is a path issue. In
Linux, most executables, like ipython, are put into /usr/bin or
/usr/local/bin. Both ipod those locations are on the shell's path-the
places it look s when you don't specify the full path of a program. On
Windows, user-installed programs don't typically get put on the path.
Check the path to make sure the directory is on there. It's probably a
similar issue with pyflakes- you didn't put the file in the place
where flatmate looks for it.
