I have a very speedy new Apple computer, but installing modules has got a little weird.

I installed XAMPP, all good so far and the Perl at /Applications/XAMPP/bin/perl seems fine.

However, I can't seem to install DBD::mysql because of some architecture mismatch.

I got the Makefile process sorted out:

/Applications/XAMPP/bin/perl Makefile.PL --mysql_config /Applications/
+XAMPP/xamppfiles/bin/mysql_config --testuser=root --libs=-L/Applicati
+ons/XAMPP/xamppfiles/lib/ --cflags=-I/Applications/XAMPP/xamppfiles/i
+nclude/
[download]

And it works just fine:

I will use the following settings for compiling and testing:

  cflags        (User's choice) = -I/Applications/XAMPP/xamppfiles/inc
+lude/
  embedded      (mysql_config ) =
  libs          (User's choice) = -L/Applications/XAMPP/xamppfiles/lib
+/
  mysql_config  (Users choice ) = /Applications/XAMPP/xamppfiles/bin/m
+ysql_config
  nocatchstderr (default      ) = 0
  nofoundrows   (default      ) = 0
  nossl         (default      ) = 0
  testdb        (User's choice) = test
  testhost      (default      ) =
  testpassword  (default      ) =
  testport      (default      ) =
  testsocket    (default      ) =
  testuser      (User's choice) = root

To change these settings, see 'perl Makefile.PL --help' and
'perldoc DBD::mysql::INSTALL'.

Checking if libs are available for compiling...
Looks good.

And make seems happy:

But make test fails bigtime because .cpan/build/DBD-mysql-4.050-0/blib/arch/auto/DBD/mysql/mysql.bundle is the wrong architecture:

So at some point I need to tell one of these processes, generating the Makefile.PL or doing the make, or both, that we're on x86_64? How do I do that exactly?

TIA
