 > I know I have `ccache_dir` configured as the default, namely
 `${portdbpath}/build/.ccache` or (expanded)
 `/opt/local/var/macports/build/.ccache`.  Could it be that because this
 directory is outside `${worksrcpath}`, the build did not have permission
 to access `${ccache_dir}` directly?  I'll try to test this when I have
 time.

 I've now tested replacing `${ccache_dir}` with `${worksrcpath}/.ccache` in
 the above section of the Portfile.  And with ccache configured, the
 building and installation of the port is now successful.  So I think the
 issue was indeed that access to `${ccache_dir}` is not permitted due to
 being outside of `${worksrcpath}`.
