A package does not install in Windows, but it should

Hello everyone. Firstly, my apologies if this is not the right place to report this problem, but my guess is that is a cabal related problem. I wrote a package and is now uploaded in Hackage [1]. I do not have any problems installing it (cabal install) in my usual computer (debian). I tried other computer running windows, and it does not build reporting the following error: hatex-guide-1.0.1.3 failed while unpacking the package. The exception was: user error (Invalid file name in tar archive: "hatex-guide-1.0.1.3\\Text\\LaTeX\\Guide\\Aux.hs") I am using a custom script and this module here (Text.LaTeX.Guide.Aux) is generated by the Setup.hs code. Suspecting that it may fail in other computers as well, I have tried to install it in yet another maching (ubuntu). It installed just fine. Therefore, I am seeing different behaviors depending on the system, when the library really does not use any platform specific feature. It should be portable if I am not missing anything. Anyway, note that the error is "while unpacking the package". Mysterious to me. I would gladly look through the Cabal code and look in which step is the error thrown, but I am not familiarized with the code of the library and it may be a big task for such a simple (in appearance) error. However, I can tell that I didn't try (yet). Any help is appreciated. Thanks, Daniel Díaz. -- [1] http://hackage.haskell.org/package/hatex-guide

This isn't quite done yet though, because backup/restore has not yet been implemented, and will require some changes to the backup/restore infrastructure because we have no way of backuping the on-disk statistics at the moment.
