Flutterby™! : suid perl alternatives

So apparently, somewhere between Ubuntu 11.10 and the Perl community, perl-suid has disappeared. What's the modern accepted alternative if you want to, say, have a CGI script (run from Apache as www-data) write data to a directory (like an image upload)?

I had been piping in to a suid Perl script whose job it was to do the security and data integrity checks before writing the file. Do I now build a C wrapper to do this?
