If this is correct, your PEAR installation is broken. PEAR 1.10.1 is  
over 5 years old.

I don't know how you installed this, but this is not the recommended  
version for the most recent version of PEAR. That you previously had  
1.4.0 speaks volumes: like PEAR, this was over 5 years old.

> Structures_Graph    1.1.1   stable
> XML_Util            1.4.5   stable

These are the recommended versions.

To fix this I would ditch the whole PEAR configuration and start out  
with a fresh install of PEAR.
