Comment (by mk@…):

 Oh, thanks for the hint. With that in mind I checked for access to that
 directory when running a build and it returned this:

 when restarting the build I see the first two folder being reused:
 {{{

 I tried to delete both folders in question:
 {{{
 $ sudo rm -rf /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/
 $ sudo rm -rf /var/folders/mp/ymsl09l9253b3vc4b2xl9pw00000gz
 }}}
 but this wouldn't change anything. Now trying to reboot the machine...
