I downloaded file:
http://downloads.sourceforge.net/gladewin32/glade-3.4.3-win32-1.zip
and when I extract it an run glade-3.exe from /bin folder, I get "no libxml2.dll" error.
Now, I want to find installer (like GTK+ bundle for GTK+) that would install glade3 and all it's dependencies for Windows XP.
