blt 2.4z-4ubuntu1 (powerpc binary) in ubuntu hardy

 BLT is a library of useful extensions for the Tcl language and the
 popular Tk graphical toolkit. It adds a vector and tree data type,
 background execution and some debugging tools to Tcl, and provides
 several new widgets for Tk, including graphs, bar-charts, trees, tabs,
 splines and hyper-links, as well as a new geometry manager, drag &
 drop support, and more.
 .
 This package contains everything you need to use BLT with your Tcl/Tk
 scripts and Tcl/Tk-enabled apps.
