That's what I get (see below). What else should I do to install gnuplot?

Do you really want to compile the Demo (with ghc)? It is already compiled if 'cabal install -fbuildExamples' was successful. Maybe you want to run 'ghci' for interactive tests. But you need to tell 'ghci' the path to the Paths module. 'make ghci-demo' should call GHCi with the right options on Linux:

$ ghci -Wall -i:src:dist/build/autogen:execute/tmp src/Demo.hs

Did I already advertise the gnuplot mailing list?
http://projects.haskell.org/cgi-bin/mailman/listinfo/gnuplot/

Yes, you did, thanks. Yet, please allow me to ask a few more questions here, before I subscribe to gnuplot list. I am really short on time - must have some plots for demo next Monday (

1) Can current version of gnuplot draw histograms? I need these first of all.
2) It seems that "$ ghci -Wall -i:src:dist/build/autogen:execute/tmp src/Demo.hs"
works on Mac OSX, yet I can't make it produce any output directly on screen.
How to generate output and display it immediately in an output window?

This is what I get:

~/wks/haskell-wks/gnuplot/gnuplot-0.4.2>ghci -Wall -i:src:dist/build/autogen:execute/tmp src/Demo.hs
GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help
