patch from Steven Jenkins <steven.jenkins@ieee.org>:

If configure attempts to build the Ruby extension on a system without a previous
installation of comedilib, compilation fails because gcc can't find comedilib.h.

The attached patch adds the distribution include directory to the gcc search
path when compiling the extension.
