[opensuse-buildservice] different control files for different debian platforms?

Is it possible to have different control files for different debian platforms? I have a package that has a Build-requires dependancy of libboost-dev for most debian platforms, however, xUbuntu 9.04 wants this to be libboost1.35-dev. Is it possible to have a control-xUbuntu_9.04 file the same way you can have a foo-Fedora_Extras_6.spec for rpm based distributions? What is the best way to handle this? I don't think you can ifdef a debian control file the way you can a rpm spec file.
