That's not 2.15 you're using there. At least, not a proper 2.15.

I get the same as you when I try a stock 5.8.2 install:

$ ~/Sandpit/582/bin/perl Test_Storable.pl 
Storable binary image v2.7 more recent than I am (v2.6) at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/_retrieve.al) line 323, at Test_Storable.pl line 10
$

However, if I build and install Storable 2.15 against 5.8.2 I see this:

$ ~/Sandpit/582/bin/perl Test_Storable.pl 
$ 

If you look at the source code for 2.15, for example here:

http://search.cpan.org/src/AMS/Storable-2.15/Storable.xs

You'll see that it has

#define STORABLE_BIN_MAJOR	2		/* Binary major "version" */
#define STORABLE_BIN_MINOR	7		/* Binary minor "version" */

so its "minor" version is 7, the same as 2.18.

Digging up the annotated change history of Storable.xs

I see that the change of MINOR from 6 to 7 was this:

http://public.activestate.com/cgi-bin/perlbrowse/p/23079

Change 23079 by nicholas@ship-in-a-bottle on 2004/07/10 21:58:34

	Store weak references.


In turn, Storable's ChangeLog suggests that that change was released as part of
version 2.11:

Sat Mar 13 20:11:03 GMT 2004   Nicholas Clark <nick@ccl4.org>
	
    Version 2.11

        1. Storing restricted hashes in canonical order would SEGV. Fixed.
        2. It was impossible to retrieve references to PL_sv_no and and
           PL_sv_undef from STORABLE_thaw hooks.
        3. restrict.t was failing on 5.8.0, due to 5.8.0's unique
           implementation of restricted hashes using PL_sv_undef
        4. These changes allow a space optimisation for restricted hashes.



Your error message implies that the Storable you have installed is version
2.10, not 2.15, as STORABLE_BIN_MINOR was changed from 5 to 6 with this:

http://public.activestate.com/cgi-bin/perlbrowse/p/17741
