Varnish not caching and error: "LIBVARNISHAPI_1.2/3 not found" on RaspberryPi

Question

Varnish serves my web page fine from a rpi, but it never caches. The Age header returned is always 0. I've made sure that there are no cookies being returned by the application. I've run with the default vcl config, but also tried forcing caching by specifying this very simple vcl_recv:

sub vcl_recv { return (hash); }

I am very new to Varnish, and may be missing something obvious. I have followed this unofficial installation guide but it looks very basic.

Here are the headers returned:

Cache-Control: public, max-age=10000

Accept-Ranges: bytes

ETag: "555-1388685308000"

X-Varnish: 32783

Age: 0

Via: 1.1 varnish

Connection: keep-alive

and sent:

Host: "my rpi host"

Accept: /

Accept-Encoding: gzip, deflate

I wanted to see some logging, but attempts to run anything but varnishd results in following errors:

$ varnishlog varnishlog: /usr/lib/arm-linux-gnueabihf/libvarnishapi.so.1: version LIBVARNISHAPI_1.2' not found (required by varnishlog) varnishlog: /usr/lib/arm-linux-gnueabihf/libvarnishapi.so.1: versionLIBVARNISHAPI_1.3' not found (required by varnishlog)

So I've tried running $ ldconfig -n /usr/local/lib/ but I get the same errors.

I've run out of ideas, what could be the issue here? I think it's very strange that the application is served, but anything else blows up.

I was missing libvarnishapi-dev. I installed it via Aptitude. There was then a mismatch with varnish(that i got from git), so I installed that through Aptitude as well.
