Hello to everyone,
First of all sorry if my question posted to this list is maybe OFF TOPIC.
Myself is using Haskell from time to time on WIN XP and OpenSuse system.
So far without a problem using RWH book as reference and 6.12 version with a lot of modules installed via cabal.
Also a Hugs install from source on my OpenSuse system only caused minor problems.setting a symlink solved the minor problem.
But what surprised me totally was that Hugs/Cabal and (or ) GHC are using shared libraries and Hugs install interfered with cabal/ghc.
I thought that both systems are totally independent from each other.Hugs a Haskell code interpreter GHV a Haskell code compiler.
But now my question :
How is it possible to run 2 different versions of GHC on the same computer ( OS , in my case OpenSuse 6.1x and hopefully 7.6 )
configure script takes a number of flags. The most
commonly used is the
--prefix=/path/to/install/in
flag, which tells the bundle that you want it to be installed in
/path/to/install/in rather than the default
location (/usr/local).
To see all the flags that configure accepts, run
configure --help.
Any search for "running GHC versions in parallel only returned results for the DPH extensions wiki but not how to run two GHC versions on the same OS.

So any feedback welcome
