varnish demon error: libvarnish.so.1 not found

In order to try out varnish for an upcoming project I installed it on an ubuntu server using this tutorial: http://varnish-cache.org/wiki/InstallationOnUbuntuDapper

The build process worked without any errors, but I cant start the varnish demon. I always get the error message

varnishd: error while loading shared libraries: libvarnish.so.1: cannot open shared object file: No such file or directory

But /usr/local/lib/libvarnish.so.1 clearly exists.

How can I tell varnish to look in that directory and load the library?

UPDATE

To answer the questions of cd34

    ldd `which varnishd`

outputs:

    linux-vdso.so.2 =>  (0x00007fff0a360000)
    libvarnish.so.1 => not found

Do you have varnish in two places on the machine, one from a previous attempt?
-> No, varnish is only installed once

Are you using 2.1.0 which was recently released?
Yes, I am using the most recent version
