It appears that threading is an optional feature in 8.4.


The Gentoo ebuild for Tcl has a "threads" option, corresponding to the
--enable-threads configure switch. However, it also has this:

pkg_setup() {
	if use threads ; then
		ewarn ""
		ewarn "PLEASE NOTE: You are compiling ${P} with"
		ewarn "threading enabled."
		ewarn "Threading is not supported by all applications"
		ewarn "that compile against tcl. You use threading at"
		ewarn "your own discretion."
		ewarn ""
		epause 5
	fi
}

My guess is that the Debian package uses threads while the FC4 version
doesn't. FWIW, my version was built without thread support.
