[IronPython] Importing NMathCore into Iron Python

[Howard R. Hansen]

When I use the following procedure to import a dynamic link math library 
into Iron Python I get the error show in the last 4 lines of the 
procedure. What am I doing wrong and what should I do to import the 
NMathCore math library into Iron Python?
