problem installing sage on mac os x 10.11.5

I am running a mac os x 10.11.5 and would like to use sage locally.

1) I first tried to install from source code. I checked that all the prerequisites were satisfied, then proceeded to download the sources, follow the steps and 'make'. it took some 10 hours; unfortunately when it finished it said it did not compile successfully.

2) so i removed the source folder from step 1, and tried the installation from binaries. I downloaded the sage-7.2-OSX_10.11.4-x86_64.dmg , then paste the folder SageMath into /Applications. When opening the sage executable, I get this error message:

ERROR:  The Sage installation tree has moved from /Users/buildslave-sage/slave/binary_pkg/build/source/SageMath/jc4b6yulaujayb9sr94ia88eourzeqip0oidma to /Applications/SageMath                                      This is not supported, and Sage will not work. To install Sage from a binary package: (....)

1. Open the .tar.bz2 archive (or .dmg on OSX)

2. Move the SageMath folder/app to where you want it to be. You can
   also rename the directory now.

3. Start sage for the first time. This will then automatically patch
   paths in binaries.

After starting Sage for the first time you cannot change the
installation any more. To install Sage elsewhere, start over from the
binary package. Or recompile Sage from scratch in the new location
("make distclean && make") here

Maybe this thread is related, but I didn't understand what's going on. I tried the csrutil disable (after step 2), but nothing changed.
