+  * react        (http://erratique.ch/software/react)

+  * lambda-term  (http://forge.ocamlcore.org/projects/lambda-term/)
+
+  Lwt must be compiled with react support, configure it with:
+
+    $ ./configure --enable-react
+
+  utop also requires OCaml compiler libraries. If you are using
+  debian, they are available as the package ocaml-compiler-libs, if
+  you are using godi, they are installed by default. If you installed
+  ocaml by hand, you can run the script utils/install-compiler-libs.sh.
