All, A friend just bought a new Mac and is trying to figure out whether they have 32 or 64 bit Ruby installed. This is the output of "file `which ruby`": /usr/bin/ruby: Mach-O universal binary with 2 architectures /usr/bin/ruby (for architecture ppc7400): Mach-O executable ppc /usr/bin/ruby (for architecture i386): Mach-O executable i386 Can't really tell from this. Does anyone know definitively if Mac OS X is still shipping with a 32 - bit version of Ruby or if there is a way to check? Thanks, Wes -- Posted via http://www.ruby-forum.com/.
