Compiling UVM with VCS

Hello -

I am new to UVM and want to compile uvm code in VCS. I downloaded UVM1.1d from Accellera website. I am using VCS Version A-2008.09.

The environment variable UVM_HOME is set to .../src/
I have tried compiling the hello_world.sv program using the following command:
vcs -sverilog +ntb_opts uvm hello_world.sv

However, I am getting the following error message
source file "uvm" cannot be opened for reading.

Any help is appreciated.

Thanks.
