error in yum

[Bob Schmidt]

Hi All,

After downloading all headers and then resolving dependencies I get this 
error:

Resolving dependencies
Traceback (most recent call last):
  File "/usr/sbin/yum", line 44, in ?
    yummain.main(sys.argv[1:])
  File "yummain.py", line 202, in main
  File "nevral.py", line 263, in resolvedeps
  File "archwork.py", line 63, in bestarch
IndexError: list index out of range

any ideas?
