When you give the path as "-pa ebin", OTP won't realize that the path
"ebin" has anything to do with the application 'MIX', so it won't look
there. (Btw., it's probably a bad idea in the long run to use uppercase
characters for an application name.)
In a proper release installation, you'd have added the path in some
other way, giving a longer path ".../MIX/ebin" or using the ERL_LIBS
environment variable to let OTP find that path for itself. But when
testing from the command line like this, you can say "-pa ../MIX/ebin"
so that the path contains the application name.
Also see section 4.4 in the book.
