Okay, I've managed to get this to work perfectly with a regular match (//) - but when I try to do a substitution(s///), the pattern fails to match anything - and no substitution is done. I'm calling the program like this: -r "s/matt/matthew/" -i -g, with the text 'matt, Matt'. Here is the code that processes the substitution bit: 
if($options{r}){
    #variable grab, add flags to pattern if they exist.
    my $pattern = $options{r};
    $pattern .= 'g' if $options{g};
    $pattern .= 'i' if $options{i};
    $pattern .= 's' if $options{s};
    
    #compile that stuff with eval
    my $compd_pattern = eval "qr($pattern)" or die $@;
    
    print "Please enter the text you wish to run the pattern on: ";
    my $text = <STDIN>;
    chomp $text;
    
#do work and display
    if($text =~ $compd_pattern){
        print $text;
    }
    else{
        print "$pattern on \n\t{$text} Failed. ";
    }
} #end R FLAG
