Finally, I discovered that buildroot needs the host to have fakeroot
installed.

I'm afraid I don't understand why that is: In my project configuration,
I do NOT have 'mark all files as owned by root' selected, so I assume
that fakeroot is not necessary in such a case. I may be wrong. Can
anyone clarify?

In any case, installing fakeroot (v1.8.1) didn't solve the problem, I am
now getting a different error message:

buildroot/build_arm/staging_dir/usr/bin/fakeroot: line  131:
buildroot/build_arm/staging_dir/usr/bin/faked: No such file or directory
fakeroot: error while starting the `faked' daemon.

Yet, the file ('faked') in question does exist:

-rwxr-xr-x 1 jg jg 42984 Nov 20 12:50
 build_arm/staging_dir/usr/bin/faked

Thank you for any help.
