CentOS - Sep 2007 - Where is the blktrace utility?

I keep reading that RHEL/CentOS 5 supports blktrace, but I can't seem
to find the blktrace/blkparse utilities.
 
Is it that just the functionality is available in the kernel, but the
user is left to have to hunt down the latest versions of the utilities
on the net?
 
If anybody knows where to get the latest versions of these utilities
I would greatly appreciate it.

I was bored so I looked around just to see if I could find this anywhere.  The
only place I found it was
http://mirror.steadfast.org/debian/pool/main/b/blktrace/blktrace_0~git-20070718142546.orig.tar.gz

Not sure if it'll work (haven't compiled/run it), but I think it's
an unpatched ver.

tarball and instructions to build... it looks quite straightforward.

The CentOS 5 kernel has CONFIG_BLK_DEV_IO_TRACE=y which is required to
use blktrace. There is no such option for the CentOS 4 kernel.
