[netcdfgroup] problem compiling netcdf-c-netcdf-4.3.0 configure missing?

I don't see the top level "configure" script after unpacking netcdf 4.3.0.
Are we supposed to create this via "autoconf"? I tried this and got

configure.ac:39: error: possibly undefined macro: AM_INIT_AUTOMAKE
     If this token and others are legitimate, please use m4_pattern_allow.
     See the Autoconf documentation.

I blindly forged ahead and ran configure getting this error message:

configure: netCDF 4.3.0
configure: error: cannot find install-sh or install.sh in "." "./.." "./../.."


Suggestions are welcome.
