Problem installing new version

I followed this istruction:, “You want to install ROOT in a fixed location, not depending on ROOTSYS…”

./configure --prefix=/usr/local
make -j2
gmake cintdlls
gmake install

/usr/local/bin/root.exe: error while loading shared libraries: cannot open shared object file: No such file or directory

this lib is now in /usr/local/lib/root/

I prefer to not use the ROOSYS environment. Thanks.
