Spamassassin from CPAN and sa-update location.

[Bookworm]

When I build SpamAssassin using the   CPAN method, it installs the test 
files (20_anti_ratware.cf and similar) in /usr/share/spamassassin.

However, sa-update shoves updates into 
/var/lib/spamassassin/3.001005/updates_spamassassin_org (with extra crap 
in /var/lib/spamassassin/3.001005/ )

I suspect that one or the other behavior is actually wrong.  Either the 
CPAN method has a bad configuration script, or the sa-update has never 
been matched to the configure script.

Either way, can anyone give me a suggestion on the best way to deal with 
this issue?  (Besides the fact that the CPAN should probably use the 
same default site rules directory as sa-update?)
