Hi,

The LIBEXEC_PREFIX shouldn't be set to this, this is actually a bug with 
beesd.in and also the sed invocation(or $TEMPLATE_COMPILER which is what 
it's called in the Makefile).

> +                      (string-append #$output all))))))))
The 'fix-path phase isn't necessary, and the LIBEXEC_PREFIX doesn't need 
to be set. The snippet below fixes the bug in bees:

>               (modules '((guix build utils)))
>               (snippet
>                #~(begin
>                    (substitute* "Defines.mk"
>                      (("^sed.*" all)
>                       (string-append all
>                                      "\t\t-e's#@DESTDIR@#$(DESTDIR)#' \\\n")))
>                    (substitute* "scripts/beesd.in"
>                      (("@LIBEXEC_PREFIX@") "@DESTDIR@/@LIBEXEC_PREFIX@"))))))

The files lib/city.cc and include/crucible/city.h need to be unbundled 
and the cityhash included in guix used instead. The cityhash package 
needs to be in the inputs, and these files need to be deleted as part of 
the snippet above:>                    (for-each delete-file
>                              '("lib/city.cc" "include/crucible/city.h"))

It appears that bees hasn't been built on a non-systemd distribution, 
because an optional feature hard fails. This fixes it, the systemd unit 
files are installed conditionally anyways:
>                    (substitute* "Makefile"
>                      (("pkg-config systemd --variable=systemdsystemunitdir" all)
>                       (string-append all " || true")))

>                    (substitute* "lib/Makefile"
>                      (("city.o.*") ""))
>                    (substitute* "src/bees-hash.cc"
>                      (("#include .crucible/city.h.") "#include <city.h>"))
These substitutions remove references to the bundled cityhash(which is 
11 years old!)

Native inputs and inputs for bees:
>     (native-inputs
>      (list pkg-config markdown))
>     (inputs
>      (list cityhash))

All the modifications made as part of the snippet should definitely be 
upstreamed, could you do that for me?
