Hello Chris,

unfortunatelly, buildroot always assumes that the "custom tarball" is on
a server where it can be fetched using wget. I submitted a patch
(http://patchwork.ozlabs.org/patch/217204/) some time ago to improve
this, but noone responded.

You can use Source Override (see docu) to use your local kernel tree
(not gzipped).

Regards

Stephan
