Trying To Compile Monodevelop

I was getting the following error when I tried to compile monodevelop 0.5.1:

././FileBrowser/FileBrowser.cs(31) error CS1527: Namespace elements 
cannot be explicitly declared as private, protected or protected internal
Compilation failed: 1 error(s), 0 warnings
make[3]: *** [MonoDevelop.Gui.Widgets.dll] Error 1
make[3]: Leaving directory 
`/usr/src/monodevelop-0.5.1/src/Libraries/MonoDevelop.Gui.Widgets'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/usr/src/monodevelop-0.5.1/src/Libraries'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/usr/src/monodevelop-0.5.1/src'
make: *** [all-recursive] Error 1

when I noticed that 0.6 was posted to the website.  However, 0.6 tells 
me I need gtk-sharp 2.0 and I must be having an off day because I can't 
seem to find a tarball for that anywhere with Google.  Any links?
