[R-SIG-Mac] Building from source problems.

[Simon Urbanek]

*sigh* Rolf, I'm giving up - your'e misquoting me and not reading my e- 
mails (if you did you'd know you don't have to bother download Xcode  
for example..). Please install release R 2.10.0 for Tiger and send me  
a private e-mail if you have issues.
For others - please do NOT follow all the attempts in this thread -  
they're all not necessary unless you want to make life hard on  
yourself (like Rolf does ;)).
