There are generous guys out there who have custom compiled packages for their own needs using different settings than might be considered standard. Some of these guys have set up their own 'repositories' for themselves, and their friends. Some of these repositories use different, or different versions of libraries required by some of the Nokia, or Maemo - let's call them standard - packages. Recovering from mismatched libraries will give you fits, even if you know what you're doing on a Linux command line. If you do get stuck in this regard, the simplest fix is to reflash! The symptom of this is finding a package listed in the package manager that says it needs an upgrade, but won't upgrade, and you can't delete either. If you encounter this situations, don't even hesitate, just reflash.
