libxt-dev 1:1.0.5-3 (ia64 binary) in ubuntu intrepid

 libXt provides the X Toolkit Intrinsics, an abstract widget library upon
 which other toolkits are based. Xt is the basis for many toolkits, including
 the Athena widgets (Xaw), and LessTif (a Motif implementation).
 .
 This package contains the development headers for the library found in
 libxt6. Non-developers likely have little use for this package.
