I don't think it was fixed yet.

Sage build/upgrade complete!

To install small scripts to directly run Sage's versions of GAP,
the PARI/GP interpreter, Maxima, or Singular etc. (by typing e.g.
just 'gap' or 'gp') into a standard 'bin' directory, start Sage
by typing 'sage' (or './sage') and enter something like

install_scripts('/usr/local/bin')

at the Sage command prompt ('sage:').

If you issued 'make', 'make all', or a similar command, then the
HTML version of the documentation will be built right now.
Otherwise, if you want to (re)build the HTML documentation,
run 'make doc'. To build the PDF version, run 'make doc-pdf'.

./sage -b

This library should not be used, the one in $SAGE_LOCAL/lib should be
used (can you check that it exists). I don't know how to fix this
though, I guess it's an OS X specific problem.

Built from scratch:
Mac OS X, 10.6.8 (Dual 6-core Xeons): no problems. Testing ('ptestlong') showed one failure:
File "/Users/Sage/sage-5.4.rc0/devel/sage-main/sage/modular/arithgroup/congroup_
generic.py", line 62:
sage: CS(2, [[1,1,0,1]])
Expected:
Congruence subgroup of SL(2,Z) of level 2, preimage of:
Matrix group over Ring of integers modulo 2 with 1 generators:
[[[1, 1], [0, 1]]]
Got:
A workspace appears to have been corrupted... automatically rebuilding (this
is harmless).
** Gap crashed or quit executing '$sage1:=ZmodnZ(2);;' **
Restarting Gap and trying again
Congruence subgroup of SL(2,Z) of level 2, preimage of:
Matrix group over Ring of integers modulo 2 with 1 generators:
[[[1, 1], [0, 1]]]
**********************************************************************

Oddly, there is no crash report from GAP, although there are 6 python 2.7 reports from around the time of this crash.

Let me know if more info is needed. Subsequent runs of the test brought success.
