Problem installing GHC 6.10.2 on Debian Etch

[Daniel van den Eijkel]

That helped.

$ aptitude remove ghc
did not remove or install any packages, but now ghc --version says 6.10.2

on the other hand, ghc 6.8.2 is still on the system

dpkg -l says
  ghc6            6.8.2dfsg1-1          GHC - the Glasgow Haskell 
Compilation system
  ghc6-doc    6.8.2dfsg1-1           Documentation for the Glasgow 
Haskell Compilation system
  ghc6-libsrc  6.6-3                      Library Sources of GHC, the 
Glasgow Haskell Compilation system
  ghc6-prof   6.8.2dfsg1-1           Profiling libraries for the Glasgow 
Haskell Compilation system

$ ls -l /usr/bin/ghc*
  /usr/bin/ghc -> /etc/alternatives/ghc
  /usr/bin/ghc6 -> ../lib/ghc-6.8.2/bin/ghc
  /usr/bin/ghc-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-6.8.2
  /usr/bin/ghci -> /etc/alternatives/ghci
  /usr/bin/ghci6 -> ../lib/ghc-6.8.2/bin/ghci
  /usr/bin/ghci-6.8.2 -> ../lib/ghc-6.8.2/bin/ghci-6.8.2
  /usr/bin/ghc-pkg -> /etc/alternatives/ghc-pkg
  /usr/bin/ghc-pkg6 -> ../lib/ghc-6.8.2/bin/ghc-pkg
  /usr/bin/ghc-pkg-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-pkg-6.8.2
  /usr/bin/ghcprof -> /etc/alternatives/ghcprof
  /usr/bin/ghcprof6 -> ../lib/ghc-6.8.2/bin/ghcprof

$ ls -l /etc/alternatives/ghc*
  /usr/bin/ghc -> /etc/alternatives/ghc
  /usr/bin/ghc6 -> ../lib/ghc-6.8.2/bin/ghc
  /usr/bin/ghc-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-6.8.2
  /usr/bin/ghci -> /etc/alternatives/ghci
  /usr/bin/ghci6 -> ../lib/ghc-6.8.2/bin/ghci
  /usr/bin/ghci-6.8.2 -> ../lib/ghc-6.8.2/bin/ghci-6.8.2
  /usr/bin/ghc-pkg -> /etc/alternatives/ghc-pkg
  /usr/bin/ghc-pkg6 -> ../lib/ghc-6.8.2/bin/ghc-pkg
  /usr/bin/ghc-pkg-6.8.2 -> ../lib/ghc-6.8.2/bin/ghc-pkg-6.8.2
  /usr/bin/ghcprof -> /etc/alternatives/ghcprof
  /usr/bin/ghcprof6 -> ../lib/ghc-6.8.2/bin/ghcprof

$ ls -l /usr/local/bin/ghc*
  /usr/local/bin/ghc -> ghc-6.10.2
  /usr/local/bin/ghc-6.10.2
  /usr/local/bin/ghci -> ghci-6.10.2
  /usr/local/bin/ghci-6.10.2
  /usr/local/bin/ghc-pkg -> ghc-pkg-6.10.2
  /usr/local/bin/ghc-pkg-6.10.2

so /usr/local/bin shadows the /usr/bin directory? I am not sure if I'm 
going to run into trouble with this installation, so I decided to 
completely uninstall the old ghc6. It removed some other packages, too:
 g++-4.1{u} ghc6 ghc6-prof{a} haskell-utils{u} libgmp3-dev{u} 
libgmpxx4ldbl{u} libncurses5-dev{u} libreadline5-dev{u} 
libstdc++6-4.1-dev{u}

After that, there was no ghc anymore except the 6.10.2 - as desired. But 
a hello-world-compilation failed because of missing lgmp. So I installed 
libgmp3-dev and libgmpxx4ldbl
Now it seems to work again, but I expect to run in trouble again. I'll 
keep you up-to-date.

Thanks,
Daniel
