Oh nice!

Right.

Good question.  I think we should try patching the Makefile.in.

This is a problem that other distros usually do not see (prefix=/usr).
There is a 3rd option: not using this define in the code, but that might
be theoretical/silly without having looked at it.

If we manage to pass a different --prefix to configure (does this work?

      #:configure-flags= '("--prefix=/usr")

then we still need to make sure that make install uses the prefix we
want by writing our own install phase...it gets ugly here I guess...
