A great reply, shmem, IMHO

Here's my present workaround based on shmem's suggestion above. Only the install sub from ExtUtils::Install is shown (it is the only place in the module file where (at present) any changes have been made). I'll post a link to a network URI where a patch can be fetched in a later update.

sub install { my($from_to,$verbose,$nonono,$inc_uninstall) = @_; $verbose ||= 0; $nonono ||= 0; my $bootstrapped = eval 'use Filesys::Type 0.02 (qw|fstype|); 1;'; + # CPAN my $no_colons_in_basenames; my @DOSish_FSTs = qw(msdos umsdos vfat ntfs iso9660 smb FAT FAT32 +CDFS NTFS); =for COMMENTARY # Types of fs that can be returned by Filesys::Type::fstype would +have been nice # to have access to without breaking into the module's encapsula +tion. (this is IMHO # nonoptimal design; these could/should have been exportable fro +m the module). =cut use Cwd qw(cwd); use ExtUtils::Packlist; use File::Basename qw(dirname); use File::Copy qw(copy); use File::Find qw(find); use File::Path qw(mkpath); use File::Compare qw(compare); my(%from_to) = %$from_to; my(%pack, $dir, $warn_permissions); my($packlist) = ExtUtils::Packlist->new(); # -w doesn't work reliably on FAT dirs # UHH, FAT-type filesystems can be found on other than MSWin32 OS' +s. Huh? XXX $warn_permissions++ if $^O eq 'MSWin32'; local(*DIR); for (qw/read write/) { $pack{$_}=$from_to{$_}; delete $from_to{$_}; } my($source_dir_or_file); foreach $source_dir_or_file (sort keys %from_to) { #Check if there are files, and if yes, look if the corresponding #target directory is writable for us opendir DIR, $source_dir_or_file or next; for (readdir DIR) { next if $_ eq $Curdir || $_ eq $Updir || $_ eq ".exists"; my $targetdir = install_rooted_dir($from_to{$source_dir_or +_file}); ++$no_colons_in_basenames if grep(fstype($targetdir) eq $_ + , @DOSish_FSTs); mkpath($targetdir) unless $nonono; if (!$nonono && !-w $targetdir) { warn "Warning: You do not have permissions to " . "install into $from_to{$source_dir_or_file}" unless $warn_permissions++; } } closedir DIR; } my $tmpfile = install_rooted_file($pack{"read"}); $packlist->read($tmpfile) if (-f $tmpfile); my $cwd = cwd(); MOD_INSTALL: foreach my $source (sort keys %from_to) { #copy the tree to the target directory without altering #timestamp and permission and remember for the .packlist #file.

    hmm.. with a context diff it would be easier to spot your changes.

    :-)

    --shmem

                                  /\_¯/(q    /

    As I read your initial post, I came up with the same idea as shmem. But after some digging, I think there's an easier solution.

    Manpage separators are provided by replace_manpage_separator() in each EU::MM_* file. But the method is only called from EU::MM_Unix::init_MAN3PODS(). So you might be able to just patch that file to do something specific instead of calling the OS-specific EU::MM_* file.

    - $manpagename = $self->replace_manpage_separator($manpagename); + $manpagename =~ s{/+}{.}g; # from MM_Cygwin.pm

    The inheritance structure is hard to follow or I'd suggest something more clever than copy/patch.
