On Windows XP, after updating to R 2.15.3 and updating all libraries, I was
no longer able to load the "oligo" package from BioConductor because of a
problem loading the "affxparser" dependency. Other packages, including BioC
ones, install and load fine.

To recreate:

source("http://bioconductor.org/biocLite.R") #install the BioC installer
biocLite("oligo")  #download and install the oligo package
library("oligo")  #attempt to load

Gets the following error:

Error in inDL(x, as.logical(local), as.logical(now), ...) :
unable to load shared object 'C:/Program
Files/R/R-2.15.3/library/affxparser/libs/i386/affxparser.dll':
LoadLibrary failure:  The specified procedure could not be found.

The file it mentions, "C:/Program
Files/R/R-2.15.3/library/affxparser/libs/i386/affxparser.dll", is right
where it's supposed to be.

Is the file corrupt, or is there another solution I haven't found?
