Apparently that broke the installation, where part of the tools still
expect /gnu/store while others expect /home/felix/gnu/store.  You can=E2=80=
=99t
avoid running =E2=80=98make clean=E2=80=99 after such a change.

However, note that using a store other than /gnu/store will prevent use
of substitutes, which may be problematic on a slow machine.
