[Mono-list] Help running F# on mono in OS X

[Jeffrey Vaughan]

Hi,

I'm trying use mono to run F# on OS X and am running into some problems.  In
particular, the fsc.exe compiler and the fsi.exe interpreter throw
exceptions on startup.

The fsharp developers indicated that this may be a bug with mono's tail call
optimization.  Another user has filed a bug report against the mono runtime
(http://bugzilla.ximian.com/show_bug.cgi?id=80326), but there has been no
follow up from the mono developers.

I'm tried mono 1.2.3.1 as well as mono 1.2.4.  My operating system is OS X
10.4 and I've tried running several versions of F#, including 1.1.13.8.
More detailed information follows.

Any help diagnosing and correcting this would be greatly appreciated, as I'd
really like to get hacking:)  Thank you!
