OSX has the "real" DTrace available by default. On Linux, this uses systemtap's dtrace emulation tool and the <sdt.h> header to convert static probes into special ELF sections describing the probe points so they may be enabled dynamically. systemtap-sdt-devel was installed onto all Linux build machines in bug 673753, so it should be valid to --enable-dtrace for both OSX and Linux. --HG-- extra : rebase_source : 480e81d27fe5c8fece172d52d16a37ae41e5993f
