Cannot compile #SNMP Change Set 41717 on Mono. Compile on Microsoft .NET is OK.
Sounds like gmcs does not work like csc for a specific LINQ expression.

    ../lib/RollingFileAppender.cs(703,59): error CS0411:  The type arguments
for method `System.Linq.Enumerable.Select<TSource,TResult>(this
System.Collections.Generic.IEnumerable<TSource>,
System.Func<TSource,int,TResult>)' cannot be inferred from the usage. Try
specifying the type arguments explicitly
