Comment (by eloy.de.enige at gmail.com):

 This is most probably a problem that your readline isn't build as a fat
 binary and so you can't build fat binaries that link against it.
 These problems are always easily recognizable by:
 {{{
 lipo: can't open input file:
 /var/folders/qi/qiRsmsrKFyGifWoVhWoCz++++TM/-Tmp-//ccyYzZ4h.out (No such
 file or directory)
 }}}

 You can check this yourself with `file`. If I use it on the default
 readline:
 {{{
 % file /usr/lib/libreadline.dylib
 /usr/lib/libreadline.dylib: Mach-O universal binary with 4 architectures
 /usr/lib/libreadline.dylib (for architecture ppc7400):  Mach-O dynamically
 linked shared library ppc
 /usr/lib/libreadline.dylib (for architecture ppc64):    Mach-O 64-bit
 dynamically linked shared library ppc64
 /usr/lib/libreadline.dylib (for architecture i386):     Mach-O dynamically
 linked shared library i386
 /usr/lib/libreadline.dylib (for architecture x86_64):   Mach-O 64-bit
 dynamically linked shared library x86_64
 }}}

 As you can see there's support for the archs ppc & i386 which are
 necessary to build macruby as a fat binary.

 Long story short: Either recompile your readline as a fat binary OR don't
 use --enable-fat-binary and only build for your native arch.
