I downloaded intltool0.35. it was an rpm package.
so i tried
#rpm -i intltool0.35.src.rpm

it was installed in an irrelevant folder.
 so i copied it to /usr/share (autoconf,automake,libtool were all there)

the error when i tried ./autogen was
 
checking for intltool >= 0.25...
  testing intltoolize... not found.
