How to build KARL

Summary

On OS X Snow Leopard I eventually gave up.  (See below for the painful memories).

When I gave up and went over to SuSE EL, I was able to follow the build instructions without any problems whatsoever.

My conclusion is that Snow Leopard has broken a number of things in various build tools and it may be some time (never?) before people go back and fix those, especially in older tool versions such as Python 2.5.

Try with Python from source

• Download Python 2.5 source from python.org
• On Snow Leopard, you have to 

• export CC=gcc-4.0 

• before you run configure otherwise you will get the error 

• cc1: error: unrecognized command line option "-Wno-long-double"

when you run make.
 
Naaa, still get this error:
