I hope this is just a typo, you missed the opening double-quote.
But you need to include $! as well so you know exactly the reason
when the open() fails.

You must treat 'perl -v' as shell command by enclosing it in the
backticks to get the output,
print FILEHANDLE `perl -v`;
More on this is in the Quote and Quote-like Operators entry in perlop
manpage.
Otherwise, bare '-v' will be treated as file test operator.
Perl has a plenty of file test operator in this form, -f to
test if the argument is a file, -d if a directory, -s to get
the size, etc. perldoc -f -X for more on this.
Anyway, is it really hard to do,
perl -v > test.txt
from the command line?
