[Mono-list] Fwd: monodoc.dll looking for missing method in mscorlib.dll

I wrote the following code:
public class MainClass
public static void Main ()
Type t1 = typeof(string);
Type t2 = typeof(string);
bool eq = t1 == t2; // comparison is
If I compiled that with mcs or gmcs, then running monodis, I see they are
aompared using a function/method called "ceq":
but if I compile with dmcs, I see System.Type::op_Equality:
IL_0018: call bool class [mscorlib]System.Type::op_Equality(class
[mscorlib]System.Type, class [mscorlib]System.Type)
both versions print "True" when run by mono from svn or stable mono 2.6.1,
but of course the second version (compiled with dmcs) can't be run on mono
2.6.1 because it doesn't support .NET 4, giving a warning of unsupported
runtime version then exception of missing method op_Equality in
/usr/lib/mono/1.0/mscorlib.dll then crashes.
does that give any insight why monodoc.dll doesn't work from svn, am I the
only one having this problem?
Thanks in advance
