Great, thanks for letting me know!
Also, Paul noted that your install directory is /root/abin. If you are installing this as root for use by others, then it is preferable to specify the binary directory, something like:
-bindir /usr/local/afni/bin
If you are the sole user on the system, then you might give your regular user sudo abilities, and do any admin steps with that. The AFNI binaries themselves can just go under the user's ~/abin directory, without any sudo rights.
Please let me know if you have any questions on this.
