Hmm well I have a problem with the installation and everything I've found so far is that I need the kernel headers. From what you're saying I understand that if I have untarred the kernel source in /usr/src and made the symbolic link the headers are already there? (the installer found the source as well via IIRC /bin/modules/2.6.7/build, which is also a symlink to /usr/src/linux) So I might have a different problem
This is because I already had to update the kernel (works fine).
Thanks for the help!
