 * Determining the location of the kernel source code
 * Found kernel source directory:
 *     /usr/src/linux
 * Found kernel object directory:
 *     /lib/modules/2.6.22-sabayon/build
 * Found sources for kernel version:
 *     2.6.22-sabayon
 * Checking for suitable kernel configuration options...
 *   ALSA is already compiled into the kernel. This is the recommended configuration, don't emerge alsa-driver.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.
 * Once you have satisfied these options, please try merging
 * this package again.
