Which version of crosstool?  0.28-rc35 is the latest, and you
probably shouldn't use anything older.

Did you read http://www.kegel.com/crosstool/crosstool-0.28-rc35/doc/crosstool-howto.html#mac ?

Where did you get your wget?  The one from fink seemed to work for me.

Now I know you didn't read http://www.kegel.com/crosstool/crosstool-0.28-rc35/doc/crosstool-howto.html#mac
as it tells you explicitly you need gnu sed.

If updating to the latest crosstool and installing the recommended gnu tools
doesn't fix this for you, we'll deal with this last problem.
