Install method for 0.7.1

Been using 0.6.1 for quite a while and thought I'd update to 0.7.1 using my standard procedure:

1. Downloading and extracting the latest version via the green button on the right side of https://launchpad.net/plank
2. installing the build dependencies: "automake autoconf intltool libtool valac libxml2-utils libgtk-3-dev libbamf3-dev libwnck-3-dev libgee-dev gnome-common"
3. Exectuing "./configure", followed by "make"
4. using "sudo checkinstall" to build and install an artificial .deb package (also tried just using "sudo make install")

However, I can't get it to work this way anymore. When I try to execute "plank" I get the following error message: "plank: error while loading shared libraries: libplank.so.0: cannot open shared object file: No such file or directory".

When I have a look into the "src" folder of the directory where I built it, there's a bash script called "plank" which works if executed manually. However the "plank" binary in "src/.libs" produces the same error message as above. I suppose it's the same binary which is installed by make.
I can't find any additional instruction in the "INSTALL" document that differ from 0.6.1.

What am I missing here?

I'm using Ubuntu 14.04.1 LTS.
