i'm wondering why if a library package (ELF system) depends on another 
dynamic loadable library.. when i link to that library, i also need to 
specify the run time paths to all the other libraries that one library 
depends on?

for example, libtiff. when i use link to a dynamic loadable libtiff, i need 
to add the -rpaths for the jpeg and the zlib as well. is that normal or am 
i missing something?
