FreeBSD7-amd64
linux_base-fc-4_14  Base set of packages needed in Linux mode (for i386/amd64)

When running the install script, I get

cat: /proc/cpuinfo: No such file or directory
Error: Your computer's processor is missing the SSE2 instructions that
        are required for MATLAB to run correctly.
        For system requirements consult http://www.mathworks.com ...

What is this /proc/cpuinfo file not found?
