You have to learn to recognize this class of error.  It means you failed to 
specify the module containing the definition of (manifest->packages) function.  

I do not use it myself, so I don’t know where it is defined.

Also, your package list construction is clunky and round-about.  I recommend 
taking a look at specification->package+output, if I recall correctly, at 
least.  I have had no issues with listing package variables directly.

I am still in the process of refactoring my module collection, but take a look 
at this file in particular to see a very different style of programming Guix.  

You are free to browse the other files for more inspiration, but be warned not 
to replicate the (@ (module) variable) syntax — it ended up backfiring in a 
most subtle of ways, and now I am undoing weeks of work to remove it.
