In the end, I ended up simply using a "system" call within Perl:
use POSIX qw(strftime);
my $gmtstring = strftime "%F %H:%I:%S", localtime;
my $filename = "symlinked-iso-file-with-limited-lifetime";
my $arg1 = ('-XP . -type l -cmin');
my $arg2 = ('+15');
my $arg3 = ('xargs rm');
system("/usr/bin/find $arg1 $arg2 | $arg3");
It's just going to have to do, until I become more proficient in Perl.
Thank you all again, for all your time, consideration, and patience
my $perl_version = "5.12.4";
