[Bug-readline] Errors installing readline on mac that already has working readline

[Gene]

I am trying to install readline for new python and ipython installation. 
I suppose it is something simple but the only specific help I found was 
from early 2000's and for asm??

System:
Max OS X 10.8.3 with latest updates for Xcode and CLT's and fortran and gcc.

I used pythonbrew to install python 3.3.0 and ipython 13.1 then switched 
to it:

pythonbrew switch 3.3.0

Any ideas?
Thanks,
Gene
