Cannot run drc from the pull-down menu in Virtuoso

[heynyo]

I installed IC 5.1.4.1 and MG Calibre 2004 on Red hat
I can stream out the layout and run DRC from command line so I think it rules out license setup problem. I also read the previous threads about setting up the pull-down menu in virtuoso and follow the steps accordingly. Finally I get to see the Calibre menu on top-right of virtuoso's toolbar.
But here comes the problem. When I click on Run DRC, nothing happened. In CIW, the message shows that DRC is invoked but nothing pops up.

Can anyone help me out?

here's some detail:

my .cshrc file

#################################################
setenv LM_LICENSE_FILE /CADTOOL/mentor/ixl_cal_2005.1_10.20/lic_cal.lic
setenv MGC_HOME /CADTOOL/mentor/ixl_cal_2005.1_10.20
set path=($path $MGC_HOME/bin)
#################################################

my .cdsinit file

###################################
load(strcat(getShellEnvVar("MGC_HOME")
"/shared/pkgs/icv.ixl/tools/queryskl/calibre.skl"))


mgc_rve_init_socket(9189)
###################################


CIW starts up with a message:

// Calibre layout-server initialized successfully at socket 9189


In the Calibre pull-down menu, everything works fine except for Run DRC and LVC and PEX buttons. After clicking them, CIW shows:

Running on Linux MOEMS 2.4.21-20.EL #1 wed Aug 18
20:58:25 EDT 2004 i686

Starting time : Wed Aug 27 13:56:41 2008

Nothing comes out. I don't know what I am missing.

Thanks for the reply.
