I successfully installed SpecTools on the Asus EeePc. However I am not running the default Xandros that the eee came with, the setup may be a little different. I will try and get instructions on how to install it on the original OS later.

If you have Hardy Heron Ubuntu 8.04, install using synaptic! 

Dependencies:

• libatk1.0-0
  (>= 1.20.0)
  

  The ATK accessibility toolkit
  

• dep:
  libc6
  (>= 2.7-1)
  

  GNU C Library: Shared libraries
  also a virtual package provided by
  libc6-udeb
  

• dep:
  libcairo2
  (>= 1.5.0)
  

  The Cairo 2D vector graphics library
  

• dep:
  libglib2.0-0
  (>= 2.15.2)
  

  The GLib library of C routines
  

• dep:
  libgtk2.0-0
  (>= 2.12.0)
  

  The GTK+ graphical user interface library
  

• dep:
  libpango1.0-0
  (>= 1.19.2)
  

  Layout and rendering of internationalized text
  

• dep:
  libusb-0.1-4
  (>= 2:0.1.12)
  

  userspace USB programming library
  

First I downloaded the package and extracted it to my desktop. Then opened up terminal and typed:

cd spectools-2007-10-R2

./configure

make

sudo cp 99-wispy.rules /etc/udev/rules.d

Then I moved spectools-2007-10-R2 folder to another location. Then to create a shortcut in my menu I went to System > Preferences > Main Menu. From their I chose the category I wanted, I put it in System Tools and clicked "New Item"

Give the item a Name "SpecTools" and then the command will be the location you chose (your/location/spectools-2007-10-R2/spectool_gtk). Click Close, and you should be done!

Note: One thing that prevented me from installing it previously was that I was trying to compile it through the GUI first, and then I was unable to do it through terminal.
