What is this problem with 'waf configure'?

[Richard Sharpe]

Fedora 14, reasonably up to date.

  File "/home/rsharpe/samba/samba.master/dynconfig/wscript", line 329,
in configure
    value = EXPAND_VARIABLES(conf, dyn_vars[varname])
  File "./buildtools/wafsamba/samba_utils.py", line 362, in EXPAND_VARIABLES
    ret = SUBST_VARS_RECURSIVE(ret, ctx.env)
  File "./buildtools/wafsamba/samba_utils.py", line 329, in SUBST_VARS_RECURSIVE
    string = subst_vars_error(string, env)
  File "./buildtools/wafsamba/samba_utils.py", line 238, in subst_vars_error
    raise KeyError("Failed to find variable %s in %s" % (vname, string))
KeyError: 'Failed to find variable PYTHONARCHDIR in ${PYTHONARCHDIR}'
