And how do I figure that out? Is there some rule of thumb? Why > wouldn't I always want the 64 version? Well, now we get back to why you were trying to install this lib in the first place. Since you have the 64bit package installed, and you felt the need to try to install it again anyway, you've either got poorly written source code that doesn't know enough to look for the 64bit libs, or you have a binary application, game or other such distraction that wants the 32bit lib for a reason. Not everything is 64bit compliant yet so sometimes you need the 32bit libs. -- This message has been double ROT13 encoded for security.
