Re: Installation of Perl/tk in 5.003_03 vs 5.004_04

[Ben Pavon <ben.pavon@hsc.hac.com>]

Hi,

I just found out that the problem has nothing to do with Perl/Tk.
Looking at my build log led me to the following code in the perl5.005_03
ExtUtils::Install module:

 #October 1997: we want to install .pm files into archlib if
 #there are any files in arch. So we depend on having ./blib/arch
 #hardcoded here.
 my $targetroot = $hash{$source};
 if ($source eq "blib/lib" and
     exists $hash{"blib/arch"} and
     directory_not_empty("blib/arch")) {
     $targetroot = $hash{"blib/arch"};
            print "Files found in blib/arch --> Installing files in "
         . "blib/lib into architecture dependend library tree!\n"
  ; #if $verbose>1;
 }

Why that change was made I would like to know. The effect for me is that
the Perl library code that used to go into the platform-dependent
directories will now be duplicated for each of the platforms we support
(4 at this time).
