BTW: you don't need to specify "--no-substitutes".  If no substitute can
be found it's going to be built locally anyway.

You need to "use" the module (gnu packages compression) which contains
the definition of the "zlib" variable.

Also, "zlib" is also the name of a license, which is why you get this
error message.  I suggest changing the module definition thus

     (define-module (ben packages my)
        #:use-module (guix packages)
        #:use-module (guix download)
        #:use-module (guix build-system gnu)
        #:use-module ((guix licenses) #:prefix license:)
        #:use-module (gnu packages compression))

And then you change

    (license lgpl3+)

in your recipe to

    (license license:lgpl3+)

Note that you'll have to "use" any modules containing package
definitions your recipe depends on.  For some inspiration feel free to
check out the bioinformatics.scm module:

    http://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/bioinformatics.scm

I often don't even have to think about how to solve problems in
packaging anymore; I just grep the sources and find the snippet or
expression I need there.
