libgnatprj4.1-dbg 4.1.2-0ubuntu4 (amd64 binary) in ubuntu feisty

 GNAT, the GNU Ada compiler, uses project files to organise source and object
 files in large-scale development efforts. Several other tools, such as
 ASIS tools (package asis-programs) and GNAT Programming Studio (package
 gnat-gps) also use project files. This library contains the necessary
 support; it was built from GNAT itself. It is licensed under the pure GPL;
 all programs that use it must also be distributed under the GPL, or not
 distributed at all.
 .
 This package contains the debugging symbols for the run-time shared library.
