Installation instructions:

1) you need the "muO dependencies" package, providing all mandatory third-party code:
http://map.squeak.org/package/3816db3a-5b3a-4868-b1ad-69200305e98c

2) unzip the muo-cache.zip archive and place the muo-cache folder in the same directory as your fresh image.

3) proceed to the installation of muO (either from a SqueakMap browser or manually by dropping the muO sar archive in a Squeak image)

Note that muO is an application for Squeak: it may not coexists happily with your other packages; it makes important changes to the look and feel of Squeak.
You should always start from a fresh image.
