Hello Willy and all

I had some problems building Sage 7.1 as well (because of pynac) but 
eventually
I could build and package it successfully, after tracking down and 
removing the
following patch:

build/pkgs/python2/patches/sys_path_security.patch

The patch is explicitly related to this bug report to upstream:

http://trac.sagemath.org/ticket/13579

I'm not sure about the actual security implications (if any) of not 
using the
patch in our SBo context, but this is the error I had when I applied it 
and the
build of pynac failed:

"not adding directory ' ' to sys.path since it's not owned by a trusted 
user."

Apparently, the patched python2 which is included in Sage didn't want to 
add
the current directory to sys.path, in order to prevent the execution of 
python
scripts from /tmp (even if I actually pointed TMP to my home directory).

Anyway, Sage 7.1 seems to be working fine here.

This is what I have done so far to the script itself, basing on the 
current
version (some of the other files were also modified - meanwhile I'll do 
some
more tests):
