Is it definitely tar that's the problem or gzip? ...

Oh! Didn't even think of that. :-% Looks like it's gzip:

evadeflow% gzip -d perl-5.14.2.tar.gz

gzip: perl-5.14.2.tar.gz: invalid compressed data--crc error


Nice find! I'll see about updating my gzip...

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:

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

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...

Is it definitely tar that's the problem or gzip? This would suggest gzip:
