We found this bug in Ubuntu (LP: #391562) but it seems to affect Debian as well:
Version 1.2.0-1 of xserver-xorg-video-sunffb has a missing line-end comma in the "Build-Dependencies" section of debian/control. There should be a comma in the area marked by ***asterisks***: Build-Depends: debhelper (>= 5), automake, libtool, xutils-dev*** ***pkg-config, xserver-xorg-dev (>= 2:1.2.99.902), x11proto-core-dev, x11proto-randr-dev, x11proto-render-dev, x11proto-xext-dev, x11proto-fonts-dev, x11proto-xf86dri-dev, x11proto-gl-dev, quilt, dpkg-dev (>= 1.14.17) -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
