Unable to determine feh PACKAGE.
This is most likely because you ran 'prove test' or 'perl test/feh.t'.
Since this test uses make variables and is therefore designed to be run from
the Makefile only, use 'make test' instead.

If you absolutely need to run it the other way, use
    PACKAGE=feh ${your_command}
