Though I will have a look upon these tickets. Thank you for the suggestion. I have made a trivial change regarding README of github already, it is ticket #19846, it needs review. Also, I haven't anywhere seen a development environment so unique and effective as Sage, involving trac tickets. I tried it for the first time with #19846 and it was a new and fresh experience for me ! I will try to do my best with the tickets.

[sage-devel] Missing file in src/build/cythonized/sage/structure/list_clone.c
Hi
The sagemath-upstream-binary in the PPA which excludes most of the src
folder, gives this error on startup:
Rewriting paths for your new installation directory
===
This might take a few minutes but only has to be done once.
patching /usr/lib/sagemath/src/build/cythonized/sage/structure/list_clone.c
Traceback (most recent call last):
File "/usr/lib/sagemath/relocate-once.py", line 85, in
p('src/build/cythonized/sage/structure/list_clone.c').substitute().save()
File "/usr/lib/sagemath/relocate-once.py", line 70, in __call__
return FilePatch(self, filename)
File "/usr/lib/sagemath/relocate-once.py", line 21, in __init__
self.st = os.stat(filename)
OSError: [Errno 2] No such file or directory:

┌┐
│ SageMath Version 6.10, Release Date: 2015-12-18│
0 jan@muizenberg:~$
Do I really need to ship this with a binary?
(I get this from sagemath-upstream-binary-full which includes the src
folder)
0 jan@muizenberg:/usr/lib/sagemath/src/build$du -hs cythonized/
318Mcythonized/
Funny thing is, basic operations ad plotting work fine, whereas I thought
if relocate-once.py failed sage would not be able to find any of it's
libraries and just crash.
Regards,
Jan

Then agani whenever starting sage. I do NOT get that when I have sagemath-upstream-binary-full installed (which includes the src folder).

[sage-devel] Re: Missing file in src/build/cythonized/sage/structure/list_clone.c
If you re-package the existing binary then you should
* first move Sage to the final directory
* then run relocate-once.py (or just start sage)
* when successful, relocate-once.py deletes itself
* then delete whatever you don't want to keep from the binary
The relocate-once.py could easily have a commanline option to patch the
paths to a different directory, right now its always the one where it
currently resides. That probably would make distro packaging easier, feel
free to send in a patch.

[sage-devel] sagenb and pycrypto
I have 7.0.beta3 installed so at some point in going from 6.10 -> 7.0.x I
had to
make distclean && make
However, in starting the notebook the warning from
local/lib/python2.7/site-packages/Crypto/Util/number.py
line 57 would appear:
# You need libgmp v5 or later to get mpz_powm_sec. Warn if it's not
available.
if _fastmath is not None and not _fastmath.HAVE_DECL_MPZ_POWM_SEC:
_warn("Not using mpz_powm_sec. You should rebuild using libgmp >= 5 to
avoid timing attack vulnerability.", PowmInsecureWarning)
Well gmp was not the issue. After rebuilding pycrypto I no longer have the
warning. I can't display the warning since rebuilding pycrypto fixed
things, but is there a missing dependency somewhere or did I just miss
something?
