MonoDevelop 0.6 installation trouble

I'm trying to install MonoDevelop 0.6

Using ./configure to install MD, I get the following error "No package 'gtksourceview-sharp-2.0' found"

Where can I get this package ?

I'm in trouble, because I've upgraded a lot of package in ordre to make MD work, and I'm bloqued right now and my 'old' MD 0.5 no more work ...

Thanks

Stéphane
