I���ve once had the same problem and asked here on Ruby Talk, but got no
satisfying answer. It is not possible without hacking mkmf, I finally
ended up putting everything in one directory. #create_makefile
(http://ruby-doc.org/stdlib-1.9.3/libdoc/mkmf/rdoc/Object.html#method-i-create_makefile)
has an option for specifying *one* subdirectory where all files reside,
but for multiple subdirectories you���d have to create multiple C extensions.

If someone knows another way to accomplish the task, I���d be intererested
in it, because large C extensions are easier organised by use of
multiple directories.
