Interesting, but I'm not sure that is what is causing the problem. On Woody:

dhoworth@pcx36:~$ perl -v

This is perl, v5.6.1 built for i386-linux

dhoworth@pcx36:~$ perl -MScalar::Util -le 'print 
Scalar::Util::looks_like_number(undef)'
1


BUT:

pcx36:~/.cpan/build/Class-DBI-0.96# make test
...
t/16-reserved.........ok
...


Perhaps also relevant is that I am using Scalar::Util 1.14 and its 
changelog says:

1.14 -- Sat May 22 08:01:19 BST 2004

Bug Fixes
   * Fixed memory leak in reduce()
   * Added tests to check passing a reference to a constant to weaken() 
in perl >= 5.008003
   * Fixed looks_like_number(undef) to return false for perl >= 5.009002
   * Fixed bug in refaddr() when passed a tied variable

ChangeLogs for releases prior to 1.14 may be found at
http://svn.mutatus.co.uk/browse/Scalar-List-Utils/tags/Scalar-List-Utils-1.13/ChangeLog


Cheers, Dave
