I guess if there is an error to be had I'd get it.
When I use ./build I get gcc: error: .c: No such file or directory. I've gone down the list in ./build and the files are there.
If I try ./update I get a /usr/bin/ld: cannot find -lopus
collect2: error: ld returned 1 exit status.
Back to V2 I guess.
