    5959for GHC is available, it will take a very long time to build by yourself.

     61Pugs needs a Parrot installation to support Perl 6 Rules.  To install Parrot, 
     62follow the instructions at http://www.parrotcode.org/.  Binary builds for 
     63Win32 is available at http://jwcs.net/~jonathan/perl6/. 
     64 
     65For dynamic loading/inlining of Haskell modules, you should install the 
     66hs-plugin library, available here: 
     67 
     68    ftp://ftp.cse.unsw.edu.au/pub/users/dons/hs-plugins/snapshots/ 
     69 
    6170To install Pugs on your system, simply type this in the command line: 
    6271 
    … …  
    6776    make install 
    6877 
    69 There is a problem on x86_64 (64 bit Athlon) machines.  See below. 
    70  
    7178Optionally you may use GHC environment variable to assign the ghc 
    7279executable path before you run "perl Makefile.PL", for example: 
    … …  
    7582    setenv GHC ${HOME}/bin/ghc (csh) 
    7683 
    77 For dynamic loading/inlining of Haskell modules, you should install the 
    78 hs-plugin library, available here:

     87GHC 6.4 has a garbage collector bug on x86_64 (64 bit Athlon) machines. 
     88Until GHC 6.4.1 is released, users on x86_64 may see crashes complaining 
     89of "strange objects".  A partial workaround is to avoid GC by requesting 
     90a large heap, using either command line arguments: 
     91 
     92    ./pugs +RTS -A200M -RTS 
     93 
     94or an environment variable: 
     95 
     96    GHCRTS='-A200M' 
     97 
     98These request a 200 MB heap, which is sufficient to run most programs. 
     99 
     100Running all tests unfortunately requires a lot more memory (perhaps 1000M). 
     101A possible alternative, which someone could explore and report on, would be to 
     102try using a 32-bit GHC instead.

    121 A possible alternative, which someone could explore and report on, would
