help,compiler error

[Eric-277]

hi guys
i search a code from url
http://langexplr.blogspot.com/2007/06/calling-boo-compiler-from-boo-program.html
and i compiler it at sharpdevelop,

it has two errors as follows

'Switch' is not a member of
'Boo.Lang.Compiler.Ast.Visitors.BooPrinterVisitor'.  (BCE0019) - C:
\Documents and Settings\Administrator\My Documents\SharpDevelop
Projects\test\test\examples\ast.boo:34,36
'Not' is not a member of 'Boo.Lang.Compiler.Ast.UnaryOperatorType'.

Here your issue is that "Switch" isn't a member of the
BooPrinterVisitor, and the operator type you are looking for is not
"Not", but "LogicalNot".

Reflector or the source are good points of information for this type of
thing.
