I don't know if I can do that yet, but I'll give it a try if I fail to  
build it.

Since I am on mac os x, I started with MySQL which is somehow  
"officially" supported by Apple, but it's a good idea indeed, I'll try  
it if I can't get anything to connect with MySQL.

Do you have any idea of why people submit patches but nobody ends up  
updating the version on hackage ?

It seems to be a great library indeed, that's why I was a bit  
surprised to see that the hackage version did not build: it would seem  
to me that it was by far the most interesting of the database library  
available on Haskell. SQL type safety is such a great feature that I  
thought nobody would want to use anything but that, apparently I was  
wrong since the other database libraries (hdbc, takusen) seem to be  
more active than haskelldb is.

Thanks again for your reply !
