[Mono-list] Latest DLR/IronPython under Mono 2.4

[Doug Blank]

I have built the nightly source #23898 of the Dynamic Language Runtime (DLR)
from:

http://www.codeplex.com/dlr/SourceControl/ListDownloadableCommits.aspx

I built this under Vista, and marked the Configuration for Release. I then
copied all of the Bin directory over to Linux, and tried running the
IronPython console program, and got the following error under Mono 2.4:

$ mono ipy.exe
IronPython 2.6 Beta (2.6.0.1) on .NET 2.0.50727.1433
Type "help", "copyright", "credits" or "license" for more information.

I am not 100% sure that I have built the DLLs correctly for mono, but I've
tried a few times, and this does work on Vista with .NET. This has worked
with earlier builds, at least with the ones that Microsoft has built (for
the example, the DLR release 0.9.0). I also get the same error in my own
hosting app.

Is this a known issue? Is it fixed in 2.6? Am I doing something wrong?

Any hints would be appreciated!
