`make byte` fails

[vasilisp]

make byte eventually fails with:

+ ocamlfind ocamlc -c -g -keep-locs -thread -syntax camlp4o -I src/lib/server -package lwt,ocsigenserver,ocsigenserver.ext,tyxml,calendar -package lwt.syntax -w +A-4-6-7-9-27-32-33-34-37-40-42-44-48 -I src/lib/server/monitor -o src/lib/server/monitor/eliom_monitor.cmo src/lib/server/monitor/eliom_monitor.ml
File "src/lib/server/monitor/eliom_monitor.ml", line 132, characters 29-69:
Error: Unbound module Eliommod_sessiongroups
Command exited with code 2.
Compilation unsuccessful after building 313 targets (3 cached) in 00:01:36.
Makefile:15: recipe for target 'byte' failed
make: *** [byte] Error 10

I haven't investigated this yet.

@glondu brought this up in the mailing list for 4.2, but unfortunately it affects master as well.

Here is an inelegant quickfix.
