To support installing libraries in my home directory, I have this in my
~/.profile

export LD_LIBRARY_PATH=$HOME/.local/lib::$LD_LIBRARY_PATH
export C_INCLUDE_PATH=$HOME/.local/include/:$C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH=$HOME/.local/include/:$CPLUS_INCLUDE_PATH
export LIBRARY_PATH=$HOME/.local/lib/:$LIBRARY_PATH
export PKG_CONFIG_PATH=$HOME/.local/lib/pkgconfig/:$PKG_CONFIG_PATH

They won't all be relevant to this case, but there's no harm in adding all
these lines to a startup file.  Of course, replace $HOME/.local/lib/ with
/usr/local/ in your case.

Cheers,
- Graham Percival
