Paul, > * read and execute on EVERY directory from the directory where the > file exists, to the root directory. That was the part that I made a mistake on. There was a directory that didn't have read access for the group, and that's why GCC's search was failing. I then ran into an error with "as" but just did a "which as" and modified its permissions to giving compiler access, and now it works fine. Thanks, I just wanted to enter this in for the next person to be able to search out. Cheers, Christopher
