Hello All,
The following patch against Open Babel 2.3.0 bypasses the mkmf-generated
makefile for installation of the Ruby bindings. It substitutes a CMake
install(FILES ...) stanza, along with a bit of setup. The choice of files to
install (only one, actually) and permissions is based on what the mkmf Makefile
does. The install location is determined based on RUBY_PREFIX and
CMAKE_INSTALL_DIR, as described in the installation docs (and contrary to what
the build system actually does in vanilla 2.3.0). This also provides DESTDIR
support implicitly.
I tested the changes on CentOS 5.5.

I hope this is acceptable.
