It is a bit odd ... 8.4 was working, and I just compiled and installed 9.2 on top of it (and created a fresh database). Oh well, I guess it will remain a mystery.

What does `ldd /usr/local/pgsql/lib/libchmoogle.so` say? What about when run under the PostgreSQL user account?

You may need to set LD_LIBRARY_PATH in the Pg startup script, or modify ld.so.conf, or re-build your extension with rpath linking enabled.
As for why it worked with 8.4 - I expect you either altered LD_LIBRARY_PATH in the 8.4 startup scripts, or maybe the 8.4 version of the extension was built with -Wl,-rpath so the paths to required libraries were embedded into the extension library.
