Hi alex. I don't understand the purpose of this change. Installing a mc package already does some pretty sophisticated pattern matching in the method InstallerMonticello>>mcThing, allowing you to install the latest version, the latest version from a particular author, or a specific version. Was there a bug in that code? Were you unaware of it? I don't understand why this is needed.
