GHC 6.10.2 will have a problem with cabal-install-0.6.2!
When I tried to install cabal-install-0.6.2 for ghc-6.10.1.20090314 I needed to change #!/bin/sh to #!/bin/bash in bootstrap.sh to avoid the following errors:
-bash-3.00$ ./bootstrap.sh Checking installed packages for ghc-6.10.1.20090314... ./bootstrap.sh: !: not found
Under Solaris sh is not bash!
Indeed. According to the OpenGroup that syntax should be fine: http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_... It works for me under Solaris 10. Perhaps Solaris 9 or older do not have a standard compliant /bin/sh program. What do you suggest we use instead as a workaround?
Next, ghc-6.10.1.20090314 comes with package unix-2.4.0.0, but cabal-install.cabal requests:
unix >= 2.0 && < 2.4
Changing to "<= 2.4" was not sufficient, so I changed it to "<= 2.5". This will affect any OS!
Hmm, it's a bit suspicious that the major version number is changing in a minor ghc release. Do we know what the API breakage is? This could affect any program. Duncan
