The usual reason a package fails with sudo is that it assumes the
$(PWD) macro will be available, pointing to the current working
directory. sudo does not preserve this environment variable, which is
often set by interactive shells.

fakeroot does not emulate root completely. It does not wrap the
access(2) systen call, which _should_ pretty much always succeed when
run as root. Succeeding can cause a test failure if the test is
testing permissions that are supposed to be denied.
