I know right to nothing about this whole xen/ocaml thing.

I attempted to rebuild it locally, and found out that
it is actually _xen_ bits which are wrong, apparently:

$ strings /usr/lib/ocaml/xenlight/xenlight.cmxa
-Wl,-rpath-link=/home/blank/debian/xen/releases/xen/xen-4.2.1/debian/build/build-utils_amd64/tools/ocaml/libs/xl/../../../../tools/blktap2/control

-Wl,-rpath-link=/home/blank/debian/xen/releases/xen/xen-4.2.1/debian/build/build-utils_amd64/tools/ocaml/libs/xl/../../../../tools/libxc
/home/blank/debian/xen/releases/xen/xen-4.2.1/debian/build/build-utils_amd64/tools/ocaml/libs/xl/../../../../tools/libxl/libxenlight.so

(which comes from libxen-ocaml-dev).  Apparently when
building xen, runtime paths weren't recorded properly.

i386 port (32bit) also has the same issue:

$ strings /usr/lib/ocaml/xenlight/xenlight.cmxa
-Wl,-rpath-link=/build/buildd-xen_4.2.1-2-i386-yflrOB/xen-4.2.1/debian/build/build-utils_i386/tools/ocaml/libs/xl/../../../../tools/blktap2/control

(both are of version 4.2.1-2).

Note also that xen-api FTBFS with xen 4.2 due to another reason,
as shown on buildd page at:
 https://buildd.debian.org/status/package.php?p=xen-api
It looks like it needs some (minimal) forward-porting to the
more recent xen API, namely xc_domain_restore():

Thanks!
