Firstly, on Solaris *NEVER* have LD_LIBRARY_PATH or LD_RUN_PATH set when 
compiling, it's just a whole world of pain that you don't need. Basically, the 
Solaris linker will forget where the libraries you linked to were if you have 
either of these environment variables set at link time. The runtime linker will 
only have its own list to fall back upon, which will be /usr/lib.

Here's how to work around it:-

In the LDFLAGS use:

LDFLAGS="-L/usr/local/BerkeleyDB/lib -R/usr/local/BerkeleyDB/lib 
-L/usr/local/lib -R/usr/local/lib"

Now, assuming that LD_LIBRARY_PATH is not defined, the linker will store in the 
resulting binary the correct search path for libraries in the correct order.
