According to autogen.sh output Perl bindings and virt tools seem to be 
missing, could it be related to this? Are the tests relying to such 
dependencies?

This is how we have configured the optional components for you today:

Daemon .............................. yes
Appliance ........................... yes
QEMU ................................ /usr/bin/qemu-system-x86_64
guestfish and C-based virt tools .... yes
FUSE filesystem ..................... no
GNU gettext for i18n ................ yes
virt-p2v ............................ no
OCaml bindings ...................... yes
OCaml-based virt tools .............. yes
Perl bindings ....................... no
Perl-based virt tools ............... no
Python bindings ..................... yes
Ruby bindings ....................... no
Java bindings ....................... yes
Haskell bindings .................... no
PHP bindings ........................ no
Erlang bindings ..................... no
Lua bindings ........................ no
Go bindings ......................... no
gobject bindings .................... no
gobject introspection ............... no
bash completion ..................... yes

Unfortunately it didn't help either.

Yes, the tests rely on Perl bindings working, so I guess you need to
install whatever missing dependencies are needed to make Perl work.

I eventually installed the list of build dependencies from the source 
package. Which theoretically means I have all the required dependencies 
for building the library.

Now it complains about missing builtin mdadm feature.

SRCDIR=. LAYOUT=partitions-md ../../run --test ./make-fedora-img.pl
md_create: feature 'mdadm' is not available in this
build of libguestfs.  Read 'AVAILABILITY' in the guestfs(3) man page for
how to check for the availability of features. at 
/home/noxdafox/development/libguestfs/test-data/phony-guests/make-fedora-img.pl 
line 103.

Is it possible to skip the build of certain images and jump directly to 
the interested one (Windows in my case)?
