sudo dtrace -n 'pid$target:someLibraryName::entry' -p <some PID>
You can include wildcards in someLibraryName using '*' or '?'. You can also put a pattern to limit functions between the two adjacent colons (the third position of the probe specifier).
You can also have DTrace launch the program instead of monitoring one that's already running by replacing '-p <PID>' with '-c <command>', but be aware that the command will run as root. That can be dangerous and it can also change the program's behavior.
