If the older and newer gdal libraries share the same soname, (which 
seems to be the case, libgdal.so.1)  what will determine the order 
of library loading at runtime is the order of the dynamic loader. 
Explicitly setting LD_LIBRARY_PATH should certainly allow to search 
first in some directory rather than another, though.

With a library like gdal, in fact, the soname doesn't really tell
much about the capabilities of the library, since it depends a lot
on the available formats and it cannot be in the ABI.
