 Erm, don't do that. If the Build-Depends are properly versioned the
backports version of the package will get pulled in, otherwise you want
(and should) build against the lenny version of the packages.

 It is common to have no preferences file at all in the build chroot,
and it isn't required.

 If the build requires the backports version of a library/package the
Build-Depends need to reflect that, otherwise the buildd network won't
be able to pick it up.

 Then the lenny version is sufficient and should get used for building.

 You should use lenny, there is no pinning involved or needed.

 As little as possible.

 So long!
