hi, I'm running gentoo/ppc on ibook rev 2.2 kernel 2.6.1_rc3 [including snd-powermac] and alsa-lib 1.0.1 when i compile jack I get following errors: [snip] checking for gethostent... yes checking for setsockopt... yes checking for connect... yes checking for on_exit... yes checking for atexit... yes JACK will use System V shm API (shmget() and friends) checking for capgetp in -lcap... no configure: WARNING: *** no libcap present configure: WARNING: *** required program md5sum not found configure: error: *** Capabilities support not present. Run configure again without --enable-capabilities. . but alsa is there and gives sound, no problems there. how to solve this? regards alex
