My bad, sorry. (I really need to read more carefully.) Here's what I get when
I add the missing lines:

evadeflow% cat > temp.sh
#!/bin/sh
needtar=1
TARVERSION=`tar --version | head -n 1 | cut -d ' ' -f 4`
float_test() {
     echo | awk 'END { exit ( !( '"$1"')); }'
}

# Tar version 1.24 and onwards handle overwriting symlinks correctly
# but earlier versions do not; this needs to work properly for sstate
float_test "$TARVERSION > 1.23" && needtar="0"
echo $needtar
evadeflow% chmod +x temp.sh
evadeflow% ./temp.sh
1

So... it correctly determines that it needs to build tar, but... the built tar
can't unpack the tarball from CPAN:

evadeflow% wget http://www.cpan.org/src/5.0/perl-5.14.2.tar.gz

./poky-git/build/tmp/sysroots/i686-linux/usr/bin/tar: Error is not
recoverable: exiting now


Weird. Anyway, I have a workaround, so it's not a big deal--especially given
that Ubuntu 10.04 isn't officially supported.  I'm happy to run any other
tests you can think of to hunt down the cause of this (I've got a pretty fast
build mchine now), but I totally understand if you've got bigger fish to fry
at the moment...
