No it doesn't exist.  There is a directory:


This is what I did to install ghc:

1) I downloaded GMP.framework and GNUreadline.framework, which my mac 
automatically unzipped and placed on my desktop.  I then dragged the 
resulting two folders into /Library/Frameworks as per the instructions at:


2) I downloaded ghc-6.8.2

3) I unzipped an untared into /Users/me/my_tar_extractions

4) I cd'ed into the newly created ghc-6.8.2 folder.

5) I read the INSTALL document in the ghc-6.8.2 folder.

6) I ran the command:

$ ./configure

7) Then I ran the command:

$ sudo make install

8)  At the end of the install output, I got a message that said:
Installation of ghc-6.8.2 was successful.

To use, add /usr/local/bin to your PATH.

Warning: this binary distribution does NOT contain documentation!

9) I appended /usr/local/bin onto the PATH in ~/.bash_profile.

After unzipping and untaring ghc, should I have put the 
ghc-6.8.2 folder in /Library/Frameworks like I did with 
GMP.framework and GNUreadline.framework?  Can I still do that?
