I am having trouble getting gdb to work properly.
I did try installing the package it wants and that makes
the err msg go way but i still cant debug like i should be able to 
e.g listing src single stepping etc.
I'm using a 2.6.38 kernel not the Mandriva kernel, but I dont think 
gdb cares? (I dont think gdb relies on some integration with the 
kernel does it?)

My make file uses these flags:
   -Wall -O0 -g3 -Werror

A typical session is shown below
Any ideas?
Thanks,
Cat22
