Installation of Intel Fortran for OS X 10.8.2 / XCode 4.6

Hi, folks - 

I'm attempting a new installation of Intel Fortran 2013.2.146 .  I'm using OS X 10.8.2 and XCode 4.6 (w/command line tools).  Unfortunately, I'm stuck right out of the gate, and all instructions that I can find are either for older versions or jump past my current sticking point.

I downloaded l_fcompxe_2013.2.146.tgz and extracted the archive.  I cd'ed into the l_fcompxe_2013.2.146 directory.  I then ran 

./install.sh

...and I immediately hit problems.  The output of the above command is

> ./install.sh
./install.sh: line 338: /sbin/ldconfig: No such file or directory
grep: /proc/cpuinfo: No such file or directory
grep: /proc/cpuinfo: No such file or directory
./install.sh: line 61: [: -lt: unary operator expected
./install.sh: line 64: [: -eq: unary operator expected
./install.sh: line 398: /Users/ryan/Downloads/l_fcompxe_2013.2.146/./pset/32e/install.32e: cannot execute binary file
./install.sh: line 399: /var/folders/gz/vhyhbgy56sv2z2fpm6wnhv280000gn/T//intel.pset.strings.ryan.ryanlaptop.local: No such file or directory

So, it looks like the installation script is not set up for 10.8 .  I'm quickly learning that OS X is anything but a "standard" linux installation. :)

Any ideas???

Thanks -
Ryan
