Subject: [rubyosx] can't build extensions as universal binaries

Hi all,

I recently installed Ruby 1.8.6 on my PPC and i386 Macs using the Ruby
One-Click Installer for OSX (http://rubyosx.rubyforge.org/), replacing
my previous manually built architecture-specific Ruby 1.8.5
installations with rubyosx's universal binary Ruby 1.8.6. However, when
I try to install appscript (http://rb-appscript.rubyforge.org),
appscript's ae.bundle extension appears to build as i386-only on both
platforms. Here's what gcc says on the PPC system:

% make
gcc -I. -I/usr/local/lib/ruby/1.8/universal-darwin8.0
-I/usr/local/lib/ruby/1.8/universal-darwin8.0 -Isrc  -fno-common -g -O2

On i386 it seems to build and work ok (though it's not universal, as I
say), although I do get the following warning:

has% make

I'd really appreciate any advice or suggestions anyone might have. As
you can imagine, it's a tad embarrassing not being able to use my own
software on my own machines :p, although at this point I don't know if
the problem lies with appscript, rubyosx, or some combination of the
two.

Many thanks,
