Merge up at http://cython.org/coercion/hgwebdir.cgi/sage-coerce-3.0.3/ (pull on top of 3.0.3 release candidate) Should build and start without problems.
Hint: If something doesn't work, try typing
sage: coercion_traceback()
which will give a listing of all errors caught in the coercion model.

Coercion doctesting
Comment from William:
teragon:sage was$ sage -coverage categories/action.pyx structure/element.pyx structure/coerce.pyx |grep SCORE SCORE categories/action.pyx: 0% (0 of 22) SCORE structure/element.pyx: 18% (28 of 153) SCORE structure/coerce.pyx: 2% (1 of 39) I tried to understand and use the coercion model code to trac down the issue with #2079 and was amazed at how nonexistent the doctesting and documentation of functions is there. In order for people to write lots of coercion code all of Sage, it's critical that they can read the coercion model code so they can track down -- for themselves -- what is going wrong when they run into trouble. I would put getting the coverage of the above files (and whatever else is related to coercion) up to 100% as the first step in your coercion model stuff. Seriously. And don't say it can't be doctested, since even though there are a lot of things not easily accessible now from the interpreter, such as the coercion model
Categories to implement
Old notes
To start, get a copy of Sage 2.10.1, install the latest cython spkg (available at http://sage.math.washington.edu/home/robertwb/cython/), pull from http://cython.org/coercion/hgwebdir.cgi/sage-coerce/ and build.
Import [attachment:fix-random.patch] to sage-scripts to ignore random tests.
