SOPC Builder - Error: Top-level design entity is undefined

I have Quartus II 10.1sp1 installed on an Ubuntu Server. I can get the tools to run, but when attempting to compile a project originally created on a Windows machine, SOPC Builder throws the following errors for each of the VIP components: 

Error: Top-level design entity "cpr" is undefined
Error: Unable to generate simulation model for cpr

I'm wondering if I'm missing an environment variable or something. Here's what I have in my bashrc: 

QUARTUS="/opt/altera/10.1/quartus/bin"
QUARTUS_ROOTDIR="/opt/altera/10.1/quartus"
SOPC_BUILDER="/opt/altera/10.1/quartus/sopc_builder/bin"
SOPC_KIT_NIOS2="/opt/altera/10.1/nios2eds"
SOPC_BUILDER_PATH_100="/opt/altera/10.1/nios2eds
QUARTUS_64BIT=1

Any ideas what could be missing?

How does everyone typically set their environment variables?

Any other ideas on what the problem might be?

    you can get case sensitivity issues going from Windows to Linux. take a look at the case of the files in the project, custom components, etc

    Thanks for the heads up. I'll have to check on that.

    I discovered that SOPC Builder will generate the system without error if I do NOT have the "create project simulator files" checkbox checked. Strange. That sounds like the issue in Windows where you have to run as Administrator.

    Confirmed that this is a bug in 10.1 that has been fixed in 11.0 and beyond.
