Rake::Filelist and symbolic links

I am using the Rake::FileList class as part of a DSL to allow users to
specify files to
include/exclude. It appears that symbolic links are not being followed
correctly, as
only directories underneath a linked directory are seen, but the files
are not seen.

Is this expected behavior?
I am using Ruby 1.8.4 and rake-0.7.3

Thanks in advance,
