Heres one I use regularly:
($VERSION) = sprintf "%d.%03d", 0, ' $Revision:: 6 $' =~ /::\s+(\S+)/;
Im not convinced that there is a security issue here to be honest. I think im with Schwern on this. If there is a security issue with version evaluation you already have serious problems. I mean presumably they could have just set up the Makefile.pl to nuke your system.....
