Missing class file in SourceForge

On line 59 of the EditManager in the latest SourceForge trunk, there is an import statement for flashx.textLayout.operations.PromoteParagraphOperation, but no such class exists in the flashx.textLayout.operations directory.  Since PromoteParagraphOperation is later used on line 1215 of EditManager, simply removing the import is not an option.

Is this a simple omission from SourceForge, or am I perhaps missing some form of build-configuration trickery that averts the compilation errors such a missing class creates?  If the latter matters, I'm using FlexBuilder 3, Flex SDK 4.1, with additional compiler arguments to pull in the config.xml and manifest.xml from the TLF svn, and including the central CoreClasses, EditClasses, and ConversionClasses classes.
