Re^2: Mac::Carbon et.c on Mac OS X 10.8

Thanks, that's helpful.

Before posting here I had already tried rebuilding Mac::Glue (as suggested in the first response to my original question), but without any luck. I was planning on next building my own perl, but then I began to suspect that the problem was more fundamental and could not be fixed by tweaking the build parameters.

Perl (v5.12.4) claims to be bi-architectural:

[kw|~] file /usr/bin/perl
/usr/bin/perl: Mach-O universal binary with 2 architectures
/usr/bin/perl (for architecture i386):    Mach-O executable i386
/usr/bin/perl (for architecture x86_64):    Mach-O 64-bit executable x
+86_64
[download]

The module I want to use is 32-bit i386:

[kw|~] lipo -info /System/Library/Perl/Extras/5.12/darwin-thread-multi
+-2level/auto/MacPerl/MacPerl.bundle
Non-fat file: /System/Library/Perl/Extras/5.12/darwin-thread-multi-2le
+vel/auto/MacPerl/MacPerl.bundle is architecture: i386
[download]

But things fail anyway:

[kw|~] perl -ce 'use Mac::Glue'
Can't load '/System/Library/Perl/Extras/5.12/darwin-thread-multi-2leve
+l/auto/MacPerl/MacPerl.bundle' for module MacPerl: dlopen(/System/Lib

I'm guessing that I'm out of luck, since the OS is 64-bit and Mac::Glue will only build as 32-bit (since it depends on the Carbon API). But I'm a novice on these architecture compatibility issues, so if someone wants to authoritatively confirm that I'm out of luck I would appreciate it.
