[BioC] C entry point "ReadHeader" not in DLL for package "affy"

[Kimpel, Mark William]

I have suddenly developed a problem with the justRMA function of package "affy". I suspected a problem with my installation and completely reinstalled R devel 2.3.0, affy, and its dependencies. The problem persists. Output is below. Ideas?


eset<-justRMA()
Error in .Call("ReadHeader", filenames[[1]], compress, PACKAGE = "affy") : 
        C entry point "ReadHeader" not in DLL for package "affy"
