These are the VMODs necessary to run ScaleSimple. We have included the 3rd party ones as submodules, to keep things simple and clean. ssutil is our vmod and should be compiled and built along with the others.
Also note, to run the geoip-vmod, you are going to need to install GeoIP Library headers. You can do this with
apt-get install libgeoip-dev
Otherwise the usual steps apply, to build the vmods
VARNISHSRC=/path/to/varnish/src VMODDIR=/path/to/compiled/vmods ./configure
make
make install
then ..
cp /path/to/compiled/vmods/* /usr/lib/varnish/vmods (or wherever your varnish lib dir is, usually /usr/lib/varnish or /usr/local/lib/varnish )
