This is nice, indeed.

$ dpkg-architecture -qDEB_BUILD_ARCH_BITS

but karmic does not know about this yet, which would be a "no" for the grid packages at least.

What we have in debian/rules of the Globus packages is

DEB_BUILD_ARCH_CPU ?= $(shell dpkg-architecture -qDEB_BUILD_ARCH_CPU)

ifneq (,$(filter $(DEB_HOST_ARCH_CPU), amd64 alpha ia64 s390x ppc64 sparc64))
flavor = gcc64pthr
enable64 = yes
flavor = gcc32pthr
enable64 = no

One could obviously combine the two approaches ...
