libxres-dev 2:1.0.3-2 (amd64 binary) in ubuntu karmic

 libXRes provides an X Window System client interface to the Resource
 extension to the X protocol.
 .
 The Resource extension allows for X clients to see and monitor the X resource
 usage of various clients (pixmaps, et al).
 .
 This package contains the development headers for the library found in
 libxres1. Non-developers likely have little use for this package.
 .
