Liam,

I'm seeing the same error when I attempt to build Macports' octave-devel on OSX 
10.7.

I've seen similar errors in the past, which those with an understanding of 
c/c++ have often fixed very quickly for me.

Eventually, I'll search through the mail-list to find one of those past 
examples. Perhaps it will be clear from that what needs to be done.

I'm in the middle of upgrading my computer, so I don't know when I'll get to it.
