A library containing code for multiple processor architectures. In my  
case, OSX for intel and ppc.

Sorry, I know absolutely nothing about automake, autoconf and these  
Anyway, I have libintl installed on my machine, so it's no longer a  
problem for me.

Hmm, well, too hard for me. I tried tweaking resulting libtool, and  
went further in the build, until stumbling on the fact that 'ar'  
doesn't like adding files with multiple architectures on an existing  
archive; creating a single archive for multiple architectures works  
though. Maybe a limitation of 'ar'.

That would do the trick, if libtool was invoked only once for all  
files, like it is the case for libgpg-error. Problem is that I don't  
know where I should patch makefiles.
I'll try to compile gpgme twice, one for each architecture, and then  
'lipo' them. And I'll post the question about GNU libtool on macosx  
mailing lists.
