Hi Matt,

Unless Paul changed something with the 10.4 build, ifeffit links with
pgplot statically, so there should never be a case where ifeffit looks
for a dynamic library for pgplot.   You can check this with
    ~>  otool -L /Applications/Ifeffit/bin/ifeffit

this is what I get:

stefano% otool -L /Applications/Ifeffit/bin/ifeffit
/Applications/Ifeffit/bin/ifeffit:
        /usr/local/lib/libpgplot.dylib (compatibility version 0.0.0, current version 0.0.0)
        /usr/X11R6/lib/libX11.6.dylib (compatibility version 6.2.0, current version 6.2.0)
        /sw/Library/Frameworks/AquaTerm.framework/Versions/A/AquaTerm (compatibility version 1.0.0, current version 1.0.0)
        /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 567.21.0)
        /usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0)
        /usr/lib/libmx.A.dylib (compatibility version 1.0.0, current version 92.0.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.2)
stefano%
This should list libX11, a curses / termcap library, and system
libraries, but not pgplot.  If it does list the dynamic pgplot
library, the build is broken.

I think it does, as far as I can tell

I believe that athena / artemis etc would have a related, but slightly
different issue. Here, you'll need to use 'otool -L' on the
Ifeffit.bundle under the /Library/Perl tree, probably
  /Library/Perl/5.8.6/darwin-trhead-something/auto/Ifeffit/Ifeffit.bundle

stefano% otool -L /Library/Perl/5.8.6/darwin-thread-multi-2level/auto/Ifeffit/Ifeffit.bundle
/Library/Perl/5.8.6/darwin-thread-multi-2level/auto/Ifeffit/Ifeffit.bundle:
        /System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 567.21.0)
        /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit (compatibility version 45.0.0, current version 824.23.0)
        /Library/Frameworks/AquaTerm.framework/Versions/A/AquaTerm (compatibility version 1.0.0, current version 1.0.0)
        /usr/X11R6/lib/libX11.6.dylib (compatibility version 6.2.0, current version 6.2.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.2)
        /usr/lib/libmx.A.dylib (compatibility version 1.0.0, current version 92.0.0)
HTH

Can anyone else confirm / deny if the installer works on OS X 10.4?

maybe I am the only one using it? :-)
Stefano
