Installation hang! Help!?

[Glenn Campbell]

Hi,
	Every time I try to install YDL 3.0 it hangs at the same place every 
time. When it is installing the XFree86 package from the CD it just 
stops and goes no further.  I am installing it on a Powerbook 3400 with 
144 MB RAM and a 20 GB HD. The entire install process goes as smooth as 
silk until it gets to this point. Could it be a bad disk? If anyone has 
any ideas please let me know. I am getting aggravated! Thanks.

Glenn
