Support for GL_ARB_texture_rectangle is now in the OpenGL package repository 
at http://darcs.haskell.org/packages/OpenGL/. I haven't released a new version 
on Hackage yet, because the support for generic vertex attributes (something 
totally unrelated to rectangular textures) hasn't been finished yet.

To explain this a bit more: I'm a bit reluctant to release an API which might 
immediately change in the next release. The tricky part here is that OpenGL 
3.1 differentiates between 3 ways of handling integral vertex attributes: 
Conversion to normalized floating point, conversion to unnormalized floating 
point, and keeping integral values. This is not yet really reflected in the 
current API in the repository.

Cheers,
