Comment:
The package installed ok, but sloane.py needs work:
{{{
sage: SloaneEncyclopedia.load()
ERROR: An unexpected error occurred while tokenizing input
The following traceback may be corrupted or invalid
The error message is: ('EOF in multi-line statement', (48, 0))

last)
/home/jaap/.sage/temp/vrede.jaapspies.nl/14953/_home_jaap__sage_init_sage_0.py
in <module>()
/home/jaap/downloads/sage-4.3.rc0/local/lib/python2.6/site-
packages/sage/databases/sloane.pyc in load(self)
246 seqnum = int(m.group('num'));
247 msg = m.group('body').strip();
--> 248 self.__data__[seqnum] = [seqnum, None,
','+msg+',']
249 verbose("Finished loading", tm)
250 self.__loaded__ = True
IndexError: list assignment index out of range
}}}
First of all there are more sequence in the databas:
{{{
class SloaneEncyclopediaClass:
"""
A local copy of the Sloane Online Encyclopedia of Integer Sequences
that contains only the sequence numbers and the sequences
themselves.
"""
def __init__(self):
"""
Initialize the database but do not load any of the data.
"""
self.__file__ = "%s/data/sloane/sloane-
oeis.bz2"%os.environ["SAGE_ROOT"]
self.__arraysize__ = 114751 # maximum sequence number + 1
self.__loaded__ = False
}}}
