[reactive] reactive 0.10.5 Install problem

[Tom Poliquin]

I hope this is the correct place to ask this.

I've been playing with Haskell for a few months (I'm a long time
imperative programmer with a couple years of Scheme)
and *still* feel like a complete newbie. It seems like there's
always something new to wrap my head around (one
could argue this makes it fun .. ?). Java never twisted
my brain :-)

I eventually want to write a simulator for an alternate computer
architecture in Haskell. . I played around with arrows and managed to 
understand the Arrow SF versions fibonacci and factorial and get them
running. 

It appears reactive may be more appropriate.

I was running ghc 6.8.3 and upgraded to 6.10.1 as it seemed
that it would be more 'reactive' friendly.
Platform is  x86_64 GNU/Linux.
All seemed to go smoothly but I can't install reactive 0.10.5.

Details of the problem are given below.

Any help greatly appreciated,

Tom
