Hi Aurel,
I have recently updated my script. Can you download the last version ? (Same link)
Personnaly, I have successfully compiled terragear with my script 3 days ago (with the latest update). I use Linux Mint 11.
If the problem still with the last update, please can you paste the content of your terminal and the content of the log file (created by the script in the script directory)
In this way I can try to help you.
Cheers,
Clément
