  Not that I know of, but I suppose that your system is broken as the
code around line 97 of demo-window.c is absolutely okay and runs on
several machines (not just mine). Which distribution are you using?

Because the library is built with libtool and the linker needs to find
the library (that's what the shell script is used for).

PS: Sorry that I couldn't really help, but I'm sure that the code works.
Feel free to file a bug report at bugzilla.gnome.org maybe others find
this issue too.
