The above is misleading.  The "error: LOOP:" is an installation warning, due to
having a dependency loop.  It is not itself an error.

In the past I've only seen this type of "mystery" failure when PSEUDO was not be
run properly.  (pseudo is being configured by the "bitbake" wrapper, located in
the scripts directory.  It has to be preloaded by the wrapper for performance
reasons during the build.)  If you are not using the bitbake wrapper script
(automatically added to your environment when you use the environment setup
script oe-init-build-env) you will need to either use the environment setup
script, or add the wrapper to your path [or call it directly].

If the wrapper is being invoked, I have some further checks to verify behavior
on your system.

If the failures continue, what type of host system do you have (distro), and
what version of libc?  Do you have both 32-bit and 64-bit libraries and
executables installed?
