Apache::DB in Devel-DebugHooks?

This is more a pause question I guess than a mod_perl one but it affects 
mod_perl:

installing Apache::DB via CPAN is for some reason installing 
Devel-DebugHooks:

https://metacpan.org/release/Devel-DebugHooks

Somehow Apache::DB is in there, but not the XS bits, so you don't get 
the .so file and so trying to use it fails.

Anyone know why Devel-DebugHooks is installing when I tell the cpan 
client to install Apache::DB?

This is the dist I was expecting to be installed:

https://metacpan.org/release/Apache-DB

And it still has the C bits that gives a working Apache::DB.
