make ptest - best way to fix errors?

edit

Hi all,

I've installed a few extra modules and run make/make ptest. A few of the tests are failing (details at the end of the post):

sage -t --warn-long 28.0 src/sage/geometry/fan.py # 4 doctests failed sage -t --warn-long 28.0 src/sage/homology/examples.py # 2 doctests failed sage -t --warn-long 28.0 src/sage/homology/chain_complex.py # 2 doctests failed

What's the best way to go about fixing these problems/figuring out what's going wrong here? Is there a protocol beyond 'post the log and open a bug on the tracker'?

I'm compiling under 64-bit OSX 10.10, with current Xcode command line tools installed.
