I wish you'd just commit the version bump instead of re-arranging all kinds of attributes for no apparent reason. This makes the diff much harder to read. I display the changes expecting a two-line change, but instead there's almost no stone left unturned. :-(

@peti, sorry for making the changes difficult to read. You could have asked me to make them differently.

This version bump needed more changes besides the new version number and checksum though:

• the upstream url has changed
• there are new dependencies
• some configure options have changed

Besides that I have also done the following with the intention to make it more readable and follow new trends I am seeing in too many nix expressions:

• listed one dependence per line
• put the dependence lists earlier
• quoted the home url

Thanks for merging.
