Final binary ("libXWImage.so") contains only the DT_SONAME name field out of
the shared library "NITF" which is set as "libNITF.so.1" string in both
"/swl/opt/ix86-linux/lib/libNITF.so" and
"/volume19/msife/users/ironst/dev/ix86-linux/lib/libNITF.so".

For proper runtime resolve you need to also provide LD_LIBRARY_PATH:

        export LD_LIBRARY_PATH=/volume19/msife/users/ironst/dev/ix86-linux/lib/
        ldd libXWImage.so
