You probably have LD_LIBRARY_PATH setup for your shell from which you 
execute the ldd command. So the lib is found.

Your librrd.so is is really in /usr/local/rrdtool-1.0.49/lib ? I'm not 
sure if it will follow symlinks.

What are makefile flags like? It is much easier need to pass in your case:
RRDLIBS = -L/usr/local/rrdtool-1.0.49/lib \
	-R/usr/local/rrdtool-1.0.49/lib -lrrd -L/usr/local/lib \
	-R/usr/local/lib -lpng

The '-R' is "A colon-separated list of directories used to  specify 
library  search  directories to the runtime linker".

Then you won't need to use env variables in the scripts.
