Hi @aswallz,
there are basically two main approaches to have interpreted Go code interacting with "outside" code:

1. from REPL, import "some/package/full/path" then use the package types, functions, variables and constants as you would normally do. This approach should just work for published packages if you run gomacro on Linux or Mac OS X, but requires several extra steps on Windows - including recompiling gomacro.
2. from compiled Go code, you can inject types, functions, variables and constants into the interpreter, then start the REPL or tell the interpreter to evaluate some string containing source code. This approach works on all platforms, and is described in more detail in _example/glycerine1/main.go and in issue #126

Yours is becoming a recurring question, ideally I should write a tutorial...
