I had a similar problem - seemed that i needed to add the machine to the 'etc/hosts' file (SUSE v9.2). I.e. underneath where localhost is defined, i added the machine IP address and machine name.

Also, (your main problem) it looks like you did not install the linux components that are distributed with foam.

gcc 4.1.2

Check the Foam installation instructions again. You need to download and install the linux/linuxAMD64 - subdirectory of third-party binary packs.
