nailgun ?

Hi guys : I got vimclojure working, and have been getting a message regarding "nailgun".

Do any of you guys use nailgun ?

Here is the message Im getting

Could not determine the Namespace of the file.

This might have different reasons. Please check, that the ng server
is running with the correct classpath and that the file does not contain
syntax errors. The interactive features will not be enabled, ie. the
keybindings will not be mapped.

Reason:
Error executing Nail! (127)

I suspect you're more likely to get an answer to that question on the main Clojure mailing list (on Google Groups) since there will be a lot more folks using nailgun and vimclojure etc.
