I followed everything as suggested on the OpenFOAM website for the current release (1.6), but I have a problem with the installation.

With order:

I've downloaded:
- OpenFOAM-1.6.General.gtgz
- ThirdParty-1.6.General.gtgz

I am trying to install OpenFOAM 1.6 on Ubuntu 9.10 Karmic Koala, 64 bit version.

When I update the environment variables by sourcing the $HOME/.bashrc file by typing in the terminal:

* . $HOME/.bashrc

I receive this message:

Warning in /home/MyUserName/OpenFOAM/OpenFOAM-1.6/etc/settings.sh:
    Cannot find /home/MyUserName/OpenFOAM/ThirdParty-1.6/gcc-4.3.3/platforms/linux64 installation.
    Please install this compiler version or if you wish to use the system compiler,
    change the 'compilerInstall' setting to 'System' in this file

On Karmic the gcc version that I am using is gcc-4.4.1 (which I think is the latest one for the moment): how can I use this compiler to make OpenFOAM work?
What actions/commands should I use?
