title: yaws not building on CentOS after erlang build OK
body: <p><strong>Problem:</strong></p>
  
  <p>yaws configure is failing after autoconf with unable to find erl </p>
  
  <p><strong>Question:</strong></p>
  
  <p>Why this error is showing, because erl can be found from a bash shell from anywhere</p>
  
  <p>which erl  --> /usr/local/bin/erl</p>
  
  <p>Thanks.</p>
