Startup failures on ubuntu

[erno]

On Ubuntu 10.04 Taiga 0.1.3 OpenSim.exe startup crashes with

** (OpenSim.exe:16828): WARNING **: The following assembly referenced from /space/src/taiga-0.1.3/taiga/bin/IronPython.dll could not be loaded:

and

I worked around by copying IronPython-2.6/*.dll to the bin directory (from IronPython-2.6-Bin.zip).

Then I get this error (TaigaWizard-generated config):

12:40:50 - [GRID SERVICE]: Region "TaigaSim" (b25f33f2-7d10-4c18-bd2f-130ad19440d7) registered successfully at 256000-256000
12:40:50 - [GRID CONNECTOR]: Registration failed: Region overlaps another region
12:40:50 - [STARTUP]: Registration of region with grid failed, aborting startup - at OpenSim.Region.Framework.Scenes.Scene.RegisterRegionWithGrid () [0x00000]
at OpenSim.OpenSimBase.CreateRegion (OpenSim.Framework.RegionInfo regionInfo, Boolean portadd_flag, Boolean do_post_init, IScene& mscene) [0x00000]

I tried changing the region location from 1000,1000 to 4000,4000 in config wizard but same result.

In robust console i get
13:05:48 - [GRID SERVICE]: Region b25f33f2-7d10-4c18-bd2f-130ad19440d7 tried to register in coordinates 256000, 256000 which are already in use in scope 00000000-0000-0000-0000-000000000000.

When I copied the configs from my taiga 0.1.2 setup and it started up. Though naali crashes
on connect, like it did with 0.1.2, but that's another story...
