I was the person that found an ocaml change that did not compile in RHEL5 
(OCaml version 3.09.3)

This was done to help catch build errors.  The fix for RHEL5 was:

[BUGFIX][PATCH 1/1] xenlight_stubs.c: Allow it to build with ocaml 3.09.3

...

+/*
+ * Starting with ocaml-3.09.3, CAMLreturn can only be used for ``value''
+ * types. CAMLreturnT was only added in 3.09.4, so we define our own
+ * version here if needed.
+ */


Hope this helps.
