It's been a while since I've had call to use an ESRI software seriously so if this seems overly simplistic or otherwise newbieish bare with me.

I'm running ArcInfo 9.3.1 and I'm trying to install the Animal Movement extesion from the USGS.  This extension depend explicitly on Spacial Analyst and thus I am posting my question here.  It's an older extention, but I need to verify some results from an existing report and I'm trying to repeat the procedure used.  I've used this extention before but it was always preinstalled on the machine.

This extention does not have an installer and basicly what I need to know (I think) is what directories are those defined by the environmental variables $AVEXT, $AVLIB, and $AVBIN.  I've taken an educated guess that Lib and Bin dirrectories in the ArcGis home directory correspond to the obvious variables, but the $AVEXT variable has me baffled.

I've also tried running the following script from a custom toolbox:

E = System.getEnvVar("AVEXT")
L = System.getEnvVar("AVLIB")
B = System.getEnvVar("AVBIN")," ",L," ",B,"")

The script runs indefinatly and never results in anything.

I need help with A: Debuging that script; B:  Information on what the defaults for those variables are; or C:  if I'm really screwing this up, instructions on how to install this extention.  If anyone can offer any advice I would appreciate it.
