I have nothing to add to my original message:

Please read it and the linked documentation carefully.

Most likely you've run ‘make install’ at some point and now have
multiple copies installed all over the place, which is why binaries
and libraries are linked to the wrong versions.

I suggest started from scratch (reinstalling your operating system),
and NOT running ’make install’ at any point.  You can use the ‘./run’
script to run things from the build directory.

More on this topic here:

No, it looks like the version of libguestfs (the shared library) and the
tools are not in sync.  Did you install it from sources, or from
self-built packages?

Those particular files are the OCaml bindings.  They are only needed
if you intend to write a brand new program in OCaml using guestfs
(http://libguestfs.org/guestfs-ocaml.3.html).  Otherwise you can
remove them without any ill effect.

However I'm surprised that whatever spec file you are using doesn't
find and package those files into two ocaml-libguestfs* subpackages.

It is.  But unless you are planning to run the external virt-v2v tests --
which you cannot do because they contain proprietary Windows binaries
and are therefore not generally released -- you don't need to compile
the test harness.

You can either uninstall ocaml-libvirt entirely (and rerun
./configure) or modify the Makefiles to not include this directory.

In the Fedora packaging we put virt-resize into libguestfs-tools-c,
but in the upstream sources the binary is built in the resize/
subdirectory.

Running ‘make’ builds all the binaries.

If you mean the binary is not being created during ‘make’, then it's
likely you have some missing build dependencies, most probably the
OCaml compiler.

It's very unclear.  What exact steps are you using to build libguestfs?
