uploading error

'rx_buffer'was not declared in this scope This is the error message that I received when trying to upload Marlin software to the Arduino 1.0.6 ide I am using a Windows 7 computer uploading this to a mega 2560 anybody else have this problem?

Sounds like there might be a mistake in the Configuration.h file. The error message will say what file and what line the error was found in. Those details would help. You can copy and paste text from the messages window just below the sketch to the forum.
