cadence verilog ams environment setup question

Wing2
I am new to verilog-ams. I keep getting the following error when creating and saving a verilog-ams cellview.

ncvlog: 07.11-s017: (c) Copyright 1995-2008 Cadence Design Systems, Inc.
`include "constants.vams"
|
ncvlog: *E,COFILX (/tmp/wtam/pdk/AMS_tutorial/a_d/verilogams/verilog.vams,3|24): cannot open include file '/usr/cds/ic-6.13/tools/spectre/etc/ahdl/constants.vams'.

ncvlog: *E,COFILX (/tmp/wtam/pdk/AMS_tutorial/a_d/verilogams/verilog.vams,4|26): cannot open include file '/usr/cds/ic-6.13/tools/spectre/etc/ahdl/disciplines.vams'.

It seems that my environment is not set up correctly such that it is looking for include files at /usr/cds/ic-6.13/tools/spectre/etc/ahdl, which no longer exists in ic6. In my environment setup I have already included:

setenv CDSDIR /usr/cds/ic-6.13
setenv MMSIMDIR /usr/cds/mmsim-7.11
setenv ASSURAHOME /usr/cds/assura-4.1
setenv AMSHOME /usr/cds/ius-8.20

setenv PATH "${MMSIMDIR}/tools/bin:${CDSDIR}/tools/dfII/bin:${CDSDIR}/tools/bin:${PATH}"
setenv PATH "${AMSHOME}/tools/bin:${AMSHOME}/tools/dfII/bin:${AMSHOME}/tools/simvision/bin:${PATH}"

Can someone tell me what is missing?

Thanks a lot!!
