Hi,
let's see what we can do:

1) If I test the new script by Bruce I get the following message:

stefano% perl Makefile.PL

 === The Ifeffit wrapper, Athena, Artemis, and Hephaestus ===

This is Mac OSX.
Checking dependencies ...
Dependencies ok.  Cool!
Reading configuration file: Ifeffit/lib/athena/athena.config
Reading configuration file: Ifeffit/lib/artemis/artemis.config
Assembled athena.pl from its parts (athena_parts/).
Assembled artemis.pl from its parts (artemis_parts/).
Assembled hephaestus.pl from its parts (hephaestus_parts/).
Fixing execution path in the Athena, Artemis, and Hephaestus executables...
  Changing athena.pl to /usr/bin/perl
  Changing artemis.pl to /usr/bin/perl
  Changing hephaestus.pl to /usr/bin/perl
  Changing ifeffit_shell.pl to /usr/bin/perl
  Changing rdaj.pl to /usr/bin/perl
  Changing atoms.pl to /usr/bin/perl
Checking if your kit is complete...
Looks good

Looks good
Writing Makefile for Archive::Zip
ERROR from evaluation of /Applications/Ifeffit/bin/horae-061/0CPAN/Makefile.PL:
ERROR from evaluation of /Applications/Ifeffit/bin/horae-061/0CPAN/Archive-Zip-1
.16/Makefile.PL: Unable to open MakeMaker.tmp: Permission denied at /System/Libr
ary/Perl/5.8.6/ExtUtils/MakeMaker.pm line 869.
# Looks like your test died before it could output anything. 

2) If I just type 'ifeffit' from the command line I get the following:

stefano% ifeffit
dyld: Library not loaded: /usr/local/lib/libpgplot.dylib
  Referenced from: /Applications/Ifeffit/bin/ifeffit
  Reason: image not found
Trace/BPT trap 

3) If, after I reinstalled everyhting from the ifeffit-1.2.8-Mac10.4.1.pkg.dmg, I launch feff from Artemis,  using one of the tutorials on copper, I get the following message:

Running feff (this could take a few minutes, please be patient) ...
Uh oh!  That Feff calculation did not run successfully.
It seems to me that not only the problem arises when an upgrade is available, but, at this stage, also with the  ifeffit-1.2.8-Mac10.4.1.pkg.dmg installer...
