[Haskell-cafe] ANNOUNCE: vacuum-cairo: a cairo frontend to vacuum for live Haskell data visualization

[Mark Wassell]

Great work. However I am have a problem running on windows - it needs 
librsvg:

Prelude System.Vacuum.Cairo> view [1]
Loading package mtl-1.1.0.2 ... linking ... done.
Loading package parallel-1.1.0.0 ... linking ... done.
Loading package glib-0.10.0 ... linking ... done.
Loading package cairo-0.10.0 ... linking ... done.
Loading package svgcairo-0.10.0 ... can't load .so/.DLL for: librsvg-2-2 
(addDLL: could not load DLL)
Prelude System.Vacuum.Cairo>

Anyone know where I can get this? I have googled around and whilst there 
is the librsvg development site, there is no sign of a windows DLL.  All 
I can find is some generic site which seems to provide DLLs. I don't 
trust it.

Cheers

Mark
