I'm not familiar with Filter::Macro, nor have I seen .plc and .pmc files be left behind after a run, and I'm not really sure how to debug the following behavior. Is this a bug in Filter::Macro? 
bash-3.2$ ls
MyPkg.pm*       foo.pl*
bash-3.2$ cat *
package MyPkg;
use Filter::Macro;
use Carp;
1;

#!/usr/bin/env perl
use MyPkg;
croak "croak";
print "not reached\n";

bash-3.2$ ./foo.pl
croak at ./foo.pl line 3
bash-3.2$ ./foo.pl
bash-3.2$ ls
MyPkg.pm*       MyPkg.pmc       foo.pl*         foo.plc
bash-3.2$ rm foo.plc
bash-3.2$ ./foo.pl
croak at ./foo.pl line 3
bash-3.2$ perl --version | sed 2q

This is perl, v5.10.1 (*) built for darwin-2level-thread-multi
