• Your shell can't find make in the PATH variable.
  Solution(s): Give which make and locate make a try.
  If any of these shell commands returns a location, add it to the path variable by using
  set path=$PATH:/location/found/by/you or
  export path=$PATH:/location/found/by/you.
  The code differences depend on the kind of shell you use.
• If the above doesn't work... you might need to install the SUN development tools/packages.
