Your joking right i cant post a f**king url , thats just bulls**t
You need 5 posts to post a URL and not, it's not "bulls**t" as people here don't really like spam.
Where did you get this archive from? It might be incomplete or corrupted. The "install.sh" is probably a dead symlink, type "ls -l" and make sure it is pointing to a real file.
Btw, why do you want to use source (and to install ALSA utils, don't you have it with your distro??) to install ALSA? You better use Centos RPM, it would be easier.
