[firedrake] Firedrake install fails

Hi, I've tried to install Firedrake on a new machine and can't seem to get passed this error. I've attached the log, where it says it fails due to an outdated autoconf dependency. I've asked IT, and they've said "The default version of autoconf on mat-lin4123 is the most recent Centos version (2.63). I've installed the EPEL version of autoconf (version 2.68), which is accessible as autoconf268." But the install script still fails with the same error. How can I work around this? Thanks Will
