a 64-bit version of the file instead of 32-bit. I don't think Larceny requires that file itself, at least not directly, so I think this problem is more likely to involve your code than Larceny's. I therefore share your skepticism about it being fixable by a rebuild of Larceny. If you do rebuild Larceny, I'd recommend Larceny v0.97 ("Funny in the Head") over v0.96. Will
