Actually I am quite surprised that that you are: a) link with the absolute path to link the so library and not use "-l rrd" b) you need to explicitly linkt libdbi again, if your code is not using it.
As for how to detect: ldd /us/lib/libdbirrd.so should show you what libraries libdbi links against dynamically - at least on linux...
