More like

    LIBS=`$(bindir)/guile-config link`

so that the guile-config is used that has just been installed,
regardless of the setting of $PATH.

Ooops.  You should document what you did somewhere if we are not going
to use it so that your work is not lost.

Are you going to you revert the changes?

Yes.  This is where the snapshot process fails:

Making all in box

The strange mention of /usr/lib/ seems to come from
libtool, which expands the "-lguile" produced by guile-config.  The
intended library /home/mvo/snaphots/install/lib/ does not
exist since "make install" has not been run (and never will).
