 This is a dependency of py25-ipython, during the build for that package,
 it arrives at this failure:

 Looks like a missing compiler command on the line that generated:
 unable to execute -fno-strict-aliasing: No such file or directory

 I'm a little concerned that the build indicates lib.macosx-10.3-i386 as
 this build is on 10.5 (Leopard).  I'm a novice with OSX, so this may be
 nothing or something useful to note.

 Thanks for getting ipython and friends onto OSX!
