In response to Lukas:
I copied all of the assemblies, along with the script, to one folder. I
attempted to add a reference to MathNet.Iridium and received the following
error:
>>> clr.AddReferenceByPartialName('MathNet.Iridium')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

This leads me to believe IronPython is having trouble loading this particular
assembly, but I cannot decode the error message. Have you ever seen this trace
before?
In Response to David:
I tried the solution you suggested with no luck. The error message I receive is
the same. I suspect that the hint I've provided above might lead us to a
solution.
Thanks All,

Hello All,
I am new to IronPython, relatively new to C#, and new to this list. I have a C#
assembly that I am attempting to access from IronPython. I am able to load the
assembly using:
clr.AddReferenceToFileAndPath(mypath)
without any problems. I can then import the classes that reside within my
assembly as well, create instances of these classes, and call certain methods
on these instances. There are methods within this assembly that rely on a
reference to another assembly (MathNet.Iridium). When I attempt to call these
methods from my IronPython script, I receive the following error:
IOError: [Errno 2] Could not load file or assembly 'MathNet.Iridium,
Version=2008.8.16.470, Culture=neutral, PublicKeyToken=c061a3ec32cc0c6f' or one
of its dependencies. The system cannot find the file specified.
Now, I never added a reference to MathNet.Iridium in my script. However, I
assumed that the C# assembly that I am calling directly was compiled with a
reference to this other assembly, and that I would not have to explicitly add a
reference. When I create a test assembly entirely in C# that calls the assembly
I am attempting to call, and do not include a reference to the MathNet.Iridium
assembly, I am able to execute the code without problems. Do I need to add a
reference to the MathNet.Iridium assembly from within my IronPython script even
though I don't intend to access it directly?
Thanks

First, try to copy all necessary assemblies to the folder with your script and
use AddReference for all of them. If that works, you can experiment with
assemblies in different folders.
Note, the path in AddReferenceToFileAndPath should be full path.
