I guess that's true if "most" is measured by number of OS's, counting 
e.g. Linux, Solaris, etc as one each. If "most" means Linux, then this 
is just plain wrong.

With LD_LIBRARY_PATH unset, ldd on my Linux system reports (as an example):
libfontconfig.so.1 => /usr/local/lib/libfontconfig.so.1
...which overrides /usr/lib/libfontconfig.so.1

On Linux, /usr/local takes precedence over /usr unless LD_LIBRARY_PATH 
is used to *prevent* that behavior.
