I don't have access to a SuSE 11.1 box, so this may or may not work, but you should be able to fix it:
1. Download the source rpm
here.
2. become root
3. rpm -i amarok-1.4.10-26.1.src.rpm
4. cd to the source directory - usually /usr/src/packages or something like that. Under it should be a few directories: SOURCE, BUILD, SPECS, etc. cd into SPECS..
5. grep Requires amarok.spec - this will spit out all thie lines referring to requirements. Make sure all the packages listed are installed. Also make sure mysql-devel and/or postgresql-devel (or whatever it's called) is installed.
6. open amarok.spec in your favourite editor. Scroll down to the line starting with ./configure. Add a line under it with the following:
--enable-mysql --enable-postgresql \
7. Save it and type:
rpmbuild -bb amarok.spec
8. If this succeeds, the last few lines will contain the locations of the resulting packages. Install them with
rpm --Uvh --oldpackage <file_name1> <file_name2> etc.
That *should* give you amarok with mysql support.
