Setools 4.1.0 emerge failure

Hi,
just emerged the new setools-4.1.0 and it falls over. I do not have X on 
this machine and it seems to fail when patching to remove the gui? Here 
are the details.

 From emerge:

[ebuild     U ~] app-admin/setools-4.1.0::gentoo [4.0.1::gentoo] USE="-X 
-debug {-test}" PYTHON_TARGETS="python2_7 python3_4 -python3_5" 0 KiB

And the error message, which comes up straight away:

 >>> Unpacking source...
 >>> Unpacking setools-4.1.0.tar.gz to 
/var/tmp/portage/app-admin/setools-4.1.0/work
 >>> Source unpacked in /var/tmp/portage/app-admin/setools-4.1.0/work
 >>> Preparing source in

Quick google suggests the patch does not match the source file? Perhaps 
most people have the X flag enabled and have not met this yet? I can 
provide full details if this is not as simple as I think.

Thanks
