One port build (www/neon29) fails for me on 9.0 (i386, freshly upgraded 
from 8.2), configure fails with the message: "cpp: error trying to exec 
'cc1': execvp: No such file or directory"
I tracked in down to the PATH variable passed to cpp, when PATH begins 
with /usr/local/bin, cpp breaks in 9.0. But when the same /usr/local/bin 
is in the end of the path it works fine.
I also noticed that in 9.0 gcc is 4.2.1 and in 8.2 gcc is 4.2.2, which 
may be related.
What might be a problem with this?

Yuri
