Comment (by jakobkroeker):

 Hello,

 this test fails on a dated gentoo(?) install
 with error
 {{{
 **********************************************************************
 File "src/sage/structure/sage_object.pyx", line 1411, in
 sage.structure.sage_object.unpickle_all
 Failed example:
     sage.structure.sage_object.unpickle_all()  # (4s on sage.math, 2011)
 Expected:

 Got:
     *** The old options style (`tar fx ...`) is highly discouraged, please
 use the modern form (leading dash before options).
     *** The standard way (with expanded options; you can still bundle
 options) for your command would be: tar -f - -x
