If you already have the Compiler Toolkit, unpack the C->Haskell sources over the toolkit sources - if you got both in one tar file, this is already done. Now go in the root directory of the Compiler Toolkit and follow the installation instructions that you are finding there - from here, they should be in `../INSTALL'. If you do not have the Compiler Toolkit, grab it from http://www.cse.unsw.edu.au/~chak/ctk/ Then, follow the above instructions.
