Solaris-style truss(1) for Mac OS X?

Even with the Developer Tools installed, my Mac OS X system has no truss(1)
command.  The FreeBSD truss command is, sadly, only a shadow of the Solaris
version.  Most critically (in my case), it has no option to trace a process
_and all of its descendents_.

Is there (any chance of getting :-) a Solaris-style truss(1) for Mac OS X?
