Thanks for the additional information. I don't know offhand how to
suppress cleaning the temporary directory. That's set by Octave
upstream rather than me.
I guess they've decided to use options that aren't supported in the
Xcode compilers for 10.6 and earlier. I've got 10.5 available right
now, so I can confirm this.
I'll probably have to force it to use gcc47 (until gcc48 is in Fink)
(gcc46 on PowerPC).
