Loading assimp

[Dlearner via Digitalmars-d-learn]

I'm trying to use assimp to load models in a program.  I see the 
Derelict binding is for version 3.3, but the assimp site has no 
binaries for this, just source.  So I try to use version 3.1.1 
and I get this error:

derelict.util.exception.SymbolLoadException at ..\..\AppData\Roaming\dub\packages\derelict-util-2.0.6\derelict-util\source\derelict\util\exception.d(35): Failed to load symbol aiReleaseExportFormatDescription from shared library assimp.dll

Is this a version problem that I need 3.3 for?  If so, I don't 
know how to build the .dll since I'm still new to programming.  
Please send help!  :)
