Running Sage under gdb is broken on OSX at the moment:

}}}
The above problem is caused by the IPython import. The problem goes away
if we disable the following libedit import test in rlineimpl.py
{{{
uses_libedit = False
if sys.platform == 'darwin' and have_readline:
import commands
(status, result) = commands.getstatusoutput( "otool -L %s | grep
libedit" % _rl.__file__ )
if status == 0 and len(result) > 0:
# we are bound to libedit - new in Leopard
_rl.parse_and_bind("bind ^I rl_complete")
print "Leopard libedit detected."
uses_libedit = True
}}}
This can be done without side effects since we link against the real
readline. The issue has been reported to the IPython mailing list.
spkg is coming up.
Cheers,
Michael
