I forgot to mention this :
I first did a make install from a mounted vfat partition and proceded with the required modprobes. After doing this, my sound worked fine but I was still getting the errors mentionned above.
I then did make uninstall thinking that the vfat mounted partition might have screwed up something.
After that, I extracted the tar file on my ext2 linux partition and redid make install. This is where I am now and getting the errors above.
