Can't install driver sk98lin for NIC (Marvell 88E8001)

[JJRabbit]

The WOL function of my NIC doesn't work in Ubuntu, for this reason I want to install the driver from Marvell. Unfortunately I can't figure out how to do this.
According to Ubuntu this NIC is in the PC:

jjr@jjr-desktop:~$ lspci | grep -i -e ethernet -e network
02:15.0 Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)

At http://www.marvell.com/ I downloaded this driver:

Driver name: Linux Driver Install Package
Platform: Linux Kernel 2.4.20 and Higher
Date: 11/3/08
Version: 10.70.2.3


When I try to run the installscript there's an error:

jjr@jjr-desktop:~$ cd Desktop
jjr@jjr-desktop:~/Desktop$ cd DriverInstall
jjr@jjr-desktop:~/Desktop/DriverInstall$ ./install.sh
./functions: 44: Syntax error: "(" unexpected
jjr@jjr-desktop:~/Desktop/DriverInstall$
