pbuilder question

[Charliej]

I am trying to setup pbuilder to use the B91dpkg-i hook to test install
my package but I seem to be having a little problem.  As you can tell
from the snippet below the build completed successfully but when dpkg -i
is run it complains of a dependency problem.   I thought that
dependencies where checked and satisfied in the first part of the build
process?  Shouldn't these dependencies still be present in the chroot
when dpkg-i is called?  Any pointers here would be greatly appreciated.

I have these set in .pbuilderrc

note:  "dpkg-deb: ignoring 1 warnings about the control file(s)" is due
to the "Homepage:" field in debian/control =)
