How has your web server been configured?

Please make sure that you can browse and clone 
http://mercurial:8000/myrepo/include/mysub directly - otherwise it will 
also not work as subrepo.

You might want to use something like
   [paths]
   / = **
in your hgweb config.

Yes, that would have been more appropriate - please make sure to remove 
-devel when you reply to this mail.
