The patch looks good. WDYT though about instead extending GUILE_SITE_DIR to search for the ccache dir and the extension dir and AC_SUBST them? It would be nice to avoid adding more ceremonial lines to configure.ac.

In that case it would work fine with 2.0. We can add more paths to the pkg-config file as well, in parallel; it's better for other build systems. Andy
