Kernel Compiling Problem

[richard <richard@spoiler.freeserve.co.uk>]

A problem has recently started compliling custom kerenels. I had to
rebuild my machine (long story)
and now the custom kernels are't build properly. The line I use to build
them is

make-kpkg --revision=custom.X.Y kernel_image

where X is usually a major change number and Y is a tweak number. eg
custom.0.1
Unfortunately ALL my kernels are now building with the custom number of
.0.1 as if I'm issuing
the line

make-kpkg --revision=custom.0.1 kernel_image

This used to work. What would everyone suggest? Removing the kernel
building package and reinstalling?
What?

Bemused...
