On Debian squeeze, one needs some OpenGL libraries to install haskell-platform-2012.4.0.0:
✗ 09:42:08 carlo@r500 ~/opt/haskell-platform-2012.4.0.0 $ ./configure --prefix=/home/carlo/opt/haskell-platform-2012.4.0.0_build
...
checking zlib.h usability... yes
checking zlib.h presence... yes
checking for zlib.h... yes
checking for zlibVersion in -lz... yes
checking GL/gl.h usability... no
checking GL/gl.h presence... no
checking for GL/gl.h... no
configure: error: The OpenGL C library is required
Solution:
sudo apt-get install libgl1-mesa-dev
libglc-dev
freeglut3-dev
libedit-dev
libglw1-mesa libglw1-mesa-dev
