IMHO, we should be able to build DTrace-ready applications on a system without DTrace installed. The whole point of the package mechanism is to be able to build on one system and run on another - consider trying to debug problems on a thin client. Ideally (IMHO), we should be able to run a DTrace-enabled application on a non-DTrace kernel (obviously without DTrace). --=20 Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour. --2E/hm+v6kSLEYT3h Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkhd9iwACgkQ/opHv/APuIepHwCfbM9kJwBcOXPSNtOqMUhd6vGr PJIAnAyUAJ8TMcqMSJi9f35tS92/cj38 =HEgg -----END PGP SIGNATURE----- --2E/hm+v6kSLEYT3h--
