There's no need to try to parse the perl -v output, which is intended
for humans and may change in future.  Using

    perl -e 'print $]'

will give you the version number in floating point format for all
versions of perl. For perl5 the format is 5.xxxyyy so testing
for >= 5.008 (or ideally 5.008001) will work fine.
