I agree, and alluded to that before. I personally haven't included any 
non-dual-lived modules as buildreqs in my own perl module packages.

However, from the point of view of consistency and simplicity, it's safe 
to build-require anything that a package "use"s, "require"s etc., i.e. 
it's harmless to add them, and the omission of core module buildreqs has 
caused problems in the past, e.g. when Data::Dumper and Digest::MD5 were 
sub-packaged. So I wouldn't be averse to a guideline that said to 
include all of them, even if they were implemented in the interpreter, 
as that's easier to understand and check than a potentially long list of 
pragmas and other exceptions.

Paul.
