[plt-scheme] Using 'lang' with relative paths in mzscheme 3.99?

Under the default module name resolver, 'mylanguage' would have to be in 
the collects directory.  However, I have a 'mylanguage.ss' in the same 
directory as the module I'm defining, and I want to be able to use a 
relative module path.

As another way of posing the question: can I use #lang where the language 
is defined in a PLaneT package?
