You can actually use 1.40 just fine.  There is a single test which
requires 1.41 (I forget now which one), and we should probably change
that test to make it conditional.  Just modify m4/guestfs-libraries.m4:

-PKG_CHECK_MODULES([LIBGUESTFS], [libguestfs >= 1.41.5])
+PKG_CHECK_MODULES([LIBGUESTFS], [libguestfs >= 1.40])

and rerun ‘autoreconf -i’.

Rich.
