It seems that the wiki page http://amarok.kde.org/wiki/Requirements:2.0 is obsolete for 2.1.

Cmake requires following dependencies :
- taglib-extras
- qtscriptgenerator
- Loudmouth
- mysql-embedded

But, where can we find the source code for these packages and which version must be used for each one ?

Copying from our current README from SVN:

What is the exact version of MySQL which is adviced ?

I used mysql-5.0.76 with Amarok 2.0.2 but when I start Amarok 2.1 beta 2 with the same mysql version, Amarok crashes during the SQL Collection import (as backtrace seems to show).
Moreover, when I clean all previous Amarok database, Amarok scans my HD but it's unable to fill the Collection : Collection is always empty.

We have a wiki page with some information about MySQL with Amarok 2:
