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/](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](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  
gcc -I. -I/usr/local/lib/ruby/1.8/universal-darwin8.0

cc -dynamic -bundle -undefined suppress -flat\_namespace -framework

/usr/lib/gcc/i686-apple-darwin8/4.0.1/…/…/…/libpthread.dylib(setreuid.So)  
definition of \_setreuid

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,
