reinstalling sdl manually on buntu - sdl

Question

I am new to doing manually installing.
I reinstalled sdl manually, now everytime I run pygame or a game that uses SDL (eg. solarwolf or supertux) I get the message: Unsupported console hardware.
I know my computer can run SDL, because it worked prior to the reinstallation.
I want to now how I can reinstall SDL properly, so that pygame will work again.
versions:
ubuntu: Ubuntu 10.04 LTS Lucid Lynx
sdl: 1.2.14
Stuff I have tried:
1)
I have tried this commandoes I found on the net:
wget http://www.libsdl.org/release/SDL-1.2.14.tar.gz
tar -xzvf SDL-1.2.14.tar.gz
cd SDL-1.2.14
./configure --prefix=$HOME
make
make install
2)
I tried again with sudo and no prefix. Maybe that wrecked some prior configurationsfile or something?
wget http://www.libsdl.org/release/SDL-1.2.14.tar.gz
tar -xzvf SDL-1.2.14.tar.gz
cd SDL-1.2.14
./configure
make
sudo make install
3)I used the Synaptic Package Manager to completely remove and reinstall all files starting with libsdl.
4)I have tried reinstalling supertux and solarwolf (with ubuntu software senter)
hoping it could resolve the problem if there were some missing dependencies.
Conclusion. I geuss a have installed sdl, but wrecked a confirgurationfile or something preventing communication between sdl and the graphic driver.
But that is a wild guess.

This sounds strange.
try: sudo ldconfig
from man ldconfig
"ldconfig creates, updates, and removes the necessary links and cache
(for use by the run-time linker, ld.so) to the most recent shared
libraries found in the directories specified on the command line, in
the file /etc/ld.so.conf, and in the trusted directories (/usr/lib and
/lib). ldconfig checks the header and file names of the libraries it
encounters when determining which versions should have their links
updated. ldconfig ignores symbolic links when scanning for libraries.
