    Are you sure that the build system finds your arm Qt ?

    If you download pre-built package, you also have to download their dependencies

          It means a package has been linked to a pretty old version of glibc. Are you sure you downloaded the latest version of the armel libraries ?

              They should be same since they are built at the same time

                  Seems there's something wrong in your dependencies. Check that you download all packages from the same distribution

                      Don't know this one, generally if I need to download precompiled package I go for the debian armel architecture.

                                You're welcome !

                                There can be several things:
                                CPU speed, RAM size/speed, bus speed, file content etc...
