xlibs-dev 1:7.2-0ubuntu11 (sparc binary) in ubuntu gutsy

 This package smooths upgrades from Debian 3.0 by depending on libice-dev,
 libsm-dev, libx11-dev, libxext-dev, libxi-dev, libxmu-dev, libxmuu-dev,
 libxpm-dev, libxrandr-dev, libxt-dev, libxtrap-dev, libxtst-dev, libxv-dev,
 x-dev, and zlib1g-dev. This transitional package is only depended upon by
 packages that haven't yet corrected their dependencies to reflect the new
 library arrangement.
 .
 If you want to install X development libraries for some purpose other than
 maintaining Debian/Ubuntu packages, then you may find the xorg-dev package
 more useful than this one.
