hp from sources under solaris

[Christian Maeder]

Hi,

installing the hp from sources does not work under solaris if /usr/sh is
no bash. Changing the starting line from #!/bin/sh to #!/bin/bash in

 haskell-platform-2011.2.0.0/scripts/install.sh
 haskell-platform-2011.2.0.0/scripts/build.sh

fixed the problem for me.

Cheers Christian
