use Perl

This is how I managed to install latest pugs on cygwin. This is the same as for any platform without existing packages.

Download and install ghc from http://www.haskell.org/ghc/download.html
    Note that from ghc 6.8 on Pugs will not compile OOTB, you'd need Cabal then.
This is a win32 native and goes into "c:/ghc/ghc-6.8.3"

Create symlinks in our path:
$ for f in ln -s /cygdrive/c/ghc/ghc-6.8.3/bin/*; do ln -s $f /usr/local/bin/; done

Download and install Cabal required for cabal-install. Cabal-1.2.4.0, which comes with ghc-6.8.3, is not new enough. Sigh.
Cabal tar.gz packages at http://hackage.haskell.org/cgi-bin/hackage-scripts/package/Cabal

wget http://hackage.haskell.org/packages/archive/Cabal/1.4.0.1/Cabal-1.4.0.1.tar.gz
tar xfz Cabal-1.4.0.1.tar.gz
cd Cabal-1.4.0.1
runhaskell ./Setup.hs configure --ghc
runhaskell ./Setup.hs build
runhaskell ./Setup.hs install
cd ..

# Get zlib and HTTP, two required deps for cabal-install:

wget http://hackage.haskell.org/packages/archive/HTTP/3001.0.4/HTTP-3001.0.4.tar.gz
tar xfz HTTP-3001.0.4.tar.gz
cd HTTP-3001.0.4.tar.gz
runhaskell ./Setup.lhs configure --ghc
runhaskell ./Setup.lhs build
runhaskell ./Setup.lhs install
cd ..

wget http://hackage.haskell.org/packages/archive/zlib/0.4.0.4/zlib-0.4.0.4.tar.gz
tar xfz zlib-0.4.0.4.tar.gz
cd zlib-0.4.0.4
runhaskell ./Setup.hs configure --ghc
runhaskell ./Setup.hs build
runhaskell ./Setup.hs install
cd ..

# now get cabal-install, which is the haskell version of CPAN.

wget http://hackage.haskell.org/packages/archive/cabal-install/0.5.1/cabal-install-0. 5.1.tar.gz
tar xfz cabal-install-0.5.1.tar.gz
cd cabal-install-0.5.1
runhaskell ./Setup.hs configure --ghc
runhaskell ./Setup.hs build
runhaskell ./Setup.hs install
cd ..

# copy the installed bin\cabal.exe to /usr/local/bin/
cp /cygdrive/c/Program\ Files/Cabal/.../bin/cabal.exe /usr/local/bin/
# and now it's getting easier:

cabal update
cabal install Pugs

# here I get a stupid regex-base-0.93.1 failure
# ghc version >=6.4 is required but it could not be found.
# The package locations are registered in C:\ghc\ghc-6.8.3\package.conf

cabal install -v regex-base
# verbose. aha, the cached tar.gz is deep there
cp 'C:/Doc..../regex-base-0.93.1.tar.gz' .
tar xfz regex-base-0.93.1.tar.gz
cd regex-base-0.93.1
runhaskell ./Setup.hs configure --ghc
# => stupid error
joe regex-base.cabal
# add Build-Type: Simple
# after Tested-With:
# Ctrl-k x
runhaskell ./Setup.hs configure --ghc
runhaskell ./Setup.hs build
runhaskell ./Setup.hs install
cd ..

# and continue...
cabal install Pugs

# dada!
cp 'C:\Program Files\Haskell\bin\pugs.exe' /usr/local/bin/
