Description
This happens on some OS X installations:
sage -t --long -force_lib devel/sage/sage/misc/interpreter.py dyld: Library not loaded: /Users/buildbot/sage-5.2/local/lib/libreadline.6.2.dylib Referenced from: /Users/buildbot/build/sage/bsd-1/bsd_upgrade_5.2/build/sage-5.7.beta2/local/lib/R//lib/libR.dylib Reason: image not found sh: line 1: 13937 Trace/BPT trap R --version ********************************************************************** File "/Users/buildbot/build/sage/bsd-1/bsd_upgrade_5.2/build/sage-5.7.beta2/devel/sage-main/sage/misc/interpreter.py", line 189: sage: os.WIFEXITED(status) and os.WEXITSTATUS(status) == 0 Expected: True Got: False **********************************************************************
The problem is that split()
doesn't do what was intented:
sage: cmd="R --version" sage: cmd.split(' |\n\t;&',1) ['R --version']

It's on OS X 10.6. I haven't determined the actual circumstances under which it occurs, but there is clearly a bug in the use of the split()
method.

Replying to kcrisman:
Is this a specific version of OS X that causes the problem?
Perhaps relocating the Sage tree causes the failure.

You're right about that bad use of split. This doesn't happen on my 10.4 or 10.7.
This is pretty new code, in a 5.7 beta - maybe the people at that patch would know more?

I think that this is a combination of a bad use of split and Sage not relocating correctly. On my OS X 10.8.2 box, I see
sage -t "devel/sage/sage/misc/interpreter.py" dyld: Library not loaded: /Users/palmieri/Desktop/Sage_stuff/sage_builds/clean/sage-5.7.beta1/local/lib/libgomp.1.dylib Referenced from: /Users/palmieri/Desktop/Sage_stuff/sage_builds/sage-5.7.beta1/local/lib/R//bin/exec/R Reason: image not found
But notice that the referenced library is supposed to be in sage_builds/clean/...
while Sage has actually been moved to sage_builds/...
.
So: the use of split should be fixed here. The rest of this is perhaps covered by #9668.

I think this patch should do it.

I doubt it, that seems to be a different issue.

Is this a specific version of OS X that causes the problem? I haven't seen this on 10.7 or 10.4.
