Greetings:

In trying to compile this from source3 downloaded from http://www.dropbox.com ...  Here is what I got on my terminal winddow:

No package 'libnautilus-extension' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables NAUTILUS_CFLAGS
and NAUTILUS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
