Corion,

Thanks for the pointer. Now my machine can recognize the latest GHC. But I still encounter such problem. Any idea why?

    The output is fairly clear:

    make: /home/neversaint/.ghc/bin/hsc2hs-6.4.1: Command not found

    So, there seems to be no file under the name /home/neversaint/.ghc/bin/hsc2hs-6.4.1, or the file is not executable. Most likely your installation of ghc is not complete or that tool needs to be built manually. I'm no expert in compiling and installing Pugs, so I recommend you take your problems to the maintainers of Pugs.

    wild guess, since I don't know about your environment and I'm also not proficient in building pugs... Seems like ghc is living in ~/.ghc/bin. You've set
    GHC=`which ghc-6.4.1` export GHC cpan Pugs

    according to Corion's advice. Now the building system is looking for hsc2hs-6.4.1 - provide it. Look for hsc2hs in ~/.ghc/bin and make a symlink to it as hsc2hs-6.4.1

    Or undefine the environment variable GHC and prepend your haskell directory to your path: PATH=~/.ghc/bin:$PATH so that the right haskell compiler is found (and the plain hsc2hs). Hope that's close to accurate and helpful ;-)

      Dear shmem,
      Look for hsc2hs in ~/.ghc/bin and make a symlink to it as hsc2hs-6.4.1
      What's the command with symlink to do that? Sorry, I'm not experienced with symlink.
      Or undefine the environment variable GHC and prepend your haskell directory to your path: PATH=~/.ghc/bin:$PATH so that the right haskell compiler is found (and the plain hsc2hs).
      I already have that in my .bash_profile:
      export PATH=$PATH:$HOME/.octave/bin:$HOME/.ghc/bin:
      And my ~/.ghc/bin directory has this:

        No, you don't have ~/.ghc/bin prepended to your $PATH. You have it appended instead, which is your original problem. When the systems looks for the "ghc" binary it will find the older install since it comes first in your path. Try this instead:
        export PATH=$HOME/.ghc/bin:$PATH
        and then try again (without exporting the GHC variable, since it should now find the correct version through the PATH variable).

    make: /home/neversaint/.ghc/bin/hsc2hs-6.4.1: Command not found make: *** src/Data/Yaml/Syck.hs Error 127

    I got this same error when trying to build it manually. I fiddled around and finally gave up.

    I was going to ask when the version of Perl6 will be ready that builds as easily and well as Perl5, based just on 'c'.


    I'm not really a human, but I play one on earth. Cogito ergo sum a bum
      And I was going to answer that, based on my experience with Perl and C, it takes at least ten years of blood, sweat, and tearing your hair out to get to that point. So you can start complaining about the rough spots in, oh, make it another four years or so. :-)
        It appears that they fixed this bug, because Pugs 6.2.13 released! compiles and works. I used the binary ghc, ghc-6.6-i386-unknown-linux.tar.bz2, installed parrot-0.4.6, and installed the lastest perl5 modules shown as dependencies. And it compiled error free, in about a half hour, and was over 10.2 megs(stripped). It seems to run, but is slower than Perl5.
