Seems you have a couple of problems:
1. you have solved yourself, it didn't work because you were not root
2. did you check if the files were copied to their location? Maybe the installation went just fine.
3. you do not have gcc installed, that's why ./configure complains. For compilation of xine you will need a huge amount of devel packages and libraries to get this running.
My solution: use pre-compiled packages from
http://packman.links2linux.de
All you are looking for is available here. You may want to add this server to the Yast installation sources for facilitated installation. Have a look in the sticky Yast update sources thread in this forum.
Have fun !
