Nokia should atleast backport its Nokia Maps software to show its commitment to code once, deploy everywhere strategy..... otherwise it is just a bag of hypocrisy
extra devel already contains Qtcomponents which are not compatible with harmattan apps ,there are missing binaries libqtcore - 4.7.4, libqtgui4 - 4.7.4, and libstdc + +6 - 4.4.0 which are some how tweaked in new Qtcomponents and thats how they were made usable.To promote a package into extra-devel one has to overwrite the old qtcomponents .Which has not been allowed ,not yet,though efforts are being made upto date . Between when a package is promoted to extra devel ,one has to take care of the updates so yeah a maintainer is needed .though hopefully when new Qtcomponents will be promoted to extra devel ,we will find a maintainer for them as well .
