omniORB4 and FRED instalation

Hello, I am trying to install FRED for testing, but I am having problems in installing all the necessary components. My problem is omniORB? I downloaded and installed omniORB4, following the instructions but still when I try to install FRED it gets the following error. checking for OMNIORB4... configure: error: Package requirements (omniORB4 != 4.1.1, omniDynamic4, omnithread3) were not met: Requested 'omniORB4 != 4.1.1' but version of omniORB4 is 4.1.1 I know that may be not directly for here my question, but can someone give me a little help in a step by step guide for installing and make the omniORB work. I have read some instructions (installing omniORB4) but after all the steps still nothing?? Thanks Adriatik
