 How to get GHC 2.02:

+The easy way is to go to the WWW GHC distribution page, which is
+self-explanatory:

+       ftp://ftp.dcs.gla.ac.uk/pub/haskell/glasgow/README.html

+----------------------------------------------------------------------
+Otherwise you can use the old anonymous FTP method from the main Haskell
 archive sites, in the directory pub/haskell/glasgow:
 
        ftp.dcs.gla.ac.uk   (130.209.240.50)
        ftp.cs.chalmers.se  (129.16.227.140)

 The Glasgow site is mirrored by src.doc.ic.ac.uk (146.169.43.1), in
