MakeMaker and Symlinks

[beppu]

I have a set of legacy perl modules that need to stay where they are on the filesystem for backwards compatibility. However, I'd like to make a CPAN-styled perl module distribution out of them. I set up another directory with the standard layout we've all come to know and love, but it's not working for me due to symlinks not being followed.

Inside the lib/ directory, I have a symlink to the directory full of legacy perl modules. Unfortunately, when I do `perl Makefile.PL; make` it doesn't pick up any of the modules because it doesn't follow the symlink. Something that does work is if I make a lib/Legacy directory and then symlink to each individule module. MakeMaker seems to follow symlinks to files but not symlinks to directories.

I don't want to have to symlink each module individually if I could avoid it. What should I do?

Modify whatever magic in MakeMaker (risky) or simply copy (or symlink) each module individually.

cat Makefile.PL
my $to_symlink =  '/blah/blah/legacy/lib';
use File::Find;
use ExtUtils::Command qw[ mkdir copy ];
my @dirs;
my @files;
find ( sub { return if $_ =~ /^\.{1,2}$/;
if( -d $File::Find::name ){
  push @dirs, $File::Find::name;
} else {
  push @files, $File::Find::name;
}
return;},$to_symlink);

s/\Q$to_symlink// for @dirs ;
mkpath @dirs;

for ( @files ){
    my $source = $_;
    s/\Q$to_symlink//;
    cp $source, $_;
}

I'm taking the symlink-every-module-individually approach. It'll do for now, and I don't really feel like modifying MakeMaker. Thanks for the reply.
