I  too  have this problem on an older Mac that I upgraded to Lion   Before reading the terminfo tip  I was able to get vi and less working by doing  export TERM xterm    After reading the tip  I grabbed  usr share terminfo from a newer Mac that has fresh install of Lion and does not exhibit this problem   Now  even though echo  TERM still yields xterm-256color  vi and less now work fine
