Not sure if it's the best fix, but you can put "export
LD_LIBRARY_PATH=/usr/local/lib" into your .bashrc, and then it will be
set for every terminal.

You might want to make it "export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib" in case something
else is already setting it - this would just add /usr/local/lib to the
existing value.

AFAIK the default search paths for ld are /lib and /usr/lib, which is
where Ubuntu packages would put their libraries. A clean Ubuntu
install has nothing in /usr/local/lib - it is for anything you're
building from source, using it isn't automatic, to prevent conflicts.
You therefore need to specify it explicitly.
