+[1] On Un*x systems, 'make install' now installs the libjpeg-turbo libraries
+into /opt/libjpeg-turbo/lib32 by default on any 32-bit system, not just x86,
+and into /opt/libjpeg-turbo/lib64 by default on any 64-bit system, not just
+x86-64.  You can override this by overriding either the 'prefix' or 'libdir'
+configure variables.
