1. Installation of DTrace on Linux (x86)
This is a Linux environment easy to set up for one's trial with DTrace:
- Ubuntu 9.10 (2.6.31-generic)
This is a short but quite precise list of steps for installation.
A. Go to ftp://crisp.dynalias.com/pub/release/website/dtrace/ to download dtrace-20091010.tar.bz2
B. Prepare utilities such as bison, flex, zlib, and libelf.
$ bunzip2 < dtrace-20091010.tar.bz2 | tar xvf -
$ sudo apt-get install bison
$ sudo apt-get install flex
$ sudo apt-get install zlib1g-dev
$ sudo apt-get install libelf-dev
$ cd dtrace-20091010
$ make all
$ sudo make install
$ sudo make load
C. Remarks
At first, I tried to install DTrace on Ubuntu 8.04 (Kernel Version 2.6.24), but in vain. The critical issue was a kernel symbol pid_task is not exported in the kernel version. The symbol is referred by the dtrace driver. The symbol seems to be exported after the kernel version 2.6.25. There were a few more issues but they were able to be easily fixed.
For my Dtrace trial, I used VMWare on iMac. The use of VMWare doesn't bother one's trial with DTrace.
Unfortunately, I couldn't find any notices from Internet on a port of DTrace on ARM. A document available in the dtrace package that I downloaded says it only supports AMD, Solaris, and X86. But I heard that iPhone OS does provide an Apple version of DTrace. iPhone 3GS is based on ARM Cortex-A8.
2. Starting DTrace
When the installed DTrace was tested according to the following tutorial, I met system hangs quite frequently.

Amit Saha once made a post about this system hang, and found out the reason: it is due to gnome-terminal, xterm, and ETerm. He suggested to use KDE konsole.

So, I did:
$ sudo apt-get install konsole
If I try DTrace on konsole, the system hang problem happens far less frequently. At least I was able to run all DTrace scripts in the tutorial without system hangs.
