Problem with fsharpi on Mac OS X: Failed to install ctrl-c handler - Ctrl-C handling will not be available

I have installed mono 2.8.1 using the package installer from mono-project.com and the f sharp libs/bins from http://fsxplat.codeplex.com/releases/view/55463.

When I run fsharpi from the Terminal, I get the following back:

Microsoft (R) F# 2.0 Interactive build
2.0.0.0 Copyright (c) Microsoft Corporation. All Rights Reserved.

For help type #help;;

Failed to install ctrl-c handler - Ctrl-C handling will not be available. Error was:  Exception has been thrown by the target of an invocation.

Sad times, I have tried running mono --verbose /usr/lib/fsharp/fsi.exe but I can't see anything helpful in the logs....

I have also tried running with all permutations of --readline- --nologo --gui- with no success :(

Does anyone have any idea why this is happening? What is more infuriating is that this seems to only be affecting me, as a friend of mine installed it fine using the exact same install method. Could MacPorts be affecting my fsharp install?

Thanks in advance for any help!

Cheers

I bet you should go to this,

https://github.com/fsharp/fsharp

which is the F# for Mono.

The CodePlex one has significant dependency on Windows.
