Erm... that *specific* bit prints nothing when pasted into a file and
executed. (Is it really supposed to?)

No, but the rest of the script (the bit following the blank line that you've
omitted) is...

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:

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...

No, but the rest of the script (the bit following the blank line that you've
omitted) is... I wanted to ensure that both the stripping out of the version
and float_test were working.

Cheers,
