Kernel 2.6 supplies the Alsa drivers; however, the alsa-drivers still try to build on hardened/x86/2.6. This profile supplies the following virtuals: virtual/linux-sources sys-kernel/hardened-dev-sources virtual/modutils sys-apps/module-init-tools virtual/os-headers sys-kernel/linux26-headers The hardened/amd64 profile also uses 2.6, and supplies the virtual/alsa virtual as below: virtual/alsa sys-kernel/hardened-dev-sources The hardened/x86/2.6 profile should also supply this virtual, as alsa is supplied by 2.6.
Fixed in CVS. thanks for reporting.
