libgnomecanvas-2.0 >= 2.0 not found. but it is installed!

Hi everyone!

I used built most of the versions of Ardour myself and it always worked fine, but now with 2.8 I got some trouble. Scons keeps telling me that I am missing libgnomecanvas-2.0 >= 2.0, even though I have libgnomecanvas-2.20 and libgnomecanvas-devel-2.20 installed.
I am using Fedora 9 with a kernel.
Can anyone please help me with this? I really want to try out the new version and especially check out the new VST support!

I appreciate the work done by Paul and the rest of the team so much! They really give a lot to both the audio community and the Linux community. Thank you so much for that!
