Script errors while livecd-creator is running yum

[Bruno Wolff III]

While trying to make a custom games livedvd I saw some script errors
and was wondering if those were packaging errors or if livecd-creator
is doing something wrong. For example:
  Installing: nethack                      ################### [ 404/1017] 
/var/tmp/rpm-tmp.ESYJZU: line 3: ln: command not found
warning: %post(nethack-3.4.3-18.fc10.i386) scriptlet failed, exit status 127
  Installing: freedroidrpg                 ################### [ 405/1017]
