This is a cool trick. On Linux, the ldd command also tells you what libraries a program wants to link to. You can also play around with LD_LIBRARY_PATH to manipulate what ldd tells you.

Binaries can also use dlopen to open libraries that aren't listed by ldd.

Good point, dlopen is fully run-time, and the strace approach will catch those too, so it's more comprehensive.
