Due to the changes to MLT, you will need the new 0.9.90 release of the build wizard, if you wish to use the wizard to build version 0.7.4 of Kdenlive.
You can get it at http://www.kde-apps.org/content/show.php/Kdenlive+Builder+Wizard?content...
Sorry about the late release.

Thanks for posting a build log! Makes it about a 1000 times easier to spot the problem.
Here is the fail from ffmpeg:
FAAD test failed.
And, here is a dump of the relevant choice from the Wizard:
FFMPEG_SUPPORT_AAC=1
If you either a) install the needed libs (as indicated in the warning under the "Advanced" button, in the tooltip and the "What's this" information) OR b) uncheck AAC support, then it should work for you.
May I recommend that you do not enable the advanced ffmpeg options until you have successfully run the wizard at least once. You can then experiment with enabling them.
Also: I am happy to learn that it is working (to some extent) in 9.04 - I have had reports indicating the opposite.
