Failed to start VisualGST

Hi there,

after many years I decided to have a look to GST again. 
I have cloned the GIT repo (on savannah) and compiled
without no extra options passed to ./configure
(commit 505aa51363c0fcee1273c301fb5760c9dcd09631, to be exact)

Then I tried to run VisualGST by

./gst-tool gst-browser and got: 

Object: DLD error: requested module gst-glib was not found

Is that a bug or did I something wrong?
