What's with /usr/local/.... /Storable ?  How many Storables do you have?

Look through your @INC.  I'll bet you have more than one.

That's just a guess and may or may not solve your problem.  From the way
the thread developed, it sure looks to me like your problem is systems 
administration and organizational.  You've clearly got a crufty system.
If you are using a distribution, like SUSE, stick with it; use their 
perl modules too wherever possible.  I'd suggest you clean it up, even 
reinstalling if that is easiest.
