 Instructions for getting a debug version of Python:

 * Download and untar sage-5.6.beta1
 * Copy the Cython spkg from #13896 to spkg/standard
 * Copy the Python spkg from #13867 to spkg/standard
 * Copy the Singular spkg from #13876 to spkg/standard
 * Copy the ZODB spkg from #10352 to spkg/standard
 * Run
   {{{
 export SAGE_DEBUG=yes
 make
   }}}
   and wait.
 * Apply the patches from #13868, #13880, #13882 and #13883 to the Sage
 library
 * Run `sage -br`

 This gives you a Sage version that starts up, but some doctests segfault.
 Probably because we just found some bugs ;-)

Comment (by SimonKing):

 I removed the phrase "At the end, Sage will die in a SIGABRT during
 "Testing startup" from the ticket description, since this is not the case
 anymore (at least not on bsd.math).
