Problem: Macports on Leopard, cannot selfupdate

[Stellit Woo]

I just switch my system to Leopard and I also need Macports same as in  
tiger.
There is no problem during the installation. But when I selfupdate  
Macports, it says I do not have an acceptable C compiler.
Following is the error message what I got

Stellit:~ stellit$ sudo port -f selfupdate
Password:
MacPorts base version 1.5 installed
Downloaded MacPorts base version 1.520

rsync.macports.org/release/base && ./configure --prefix=/opt/local --

Library/Tcl && make && make install" returned error 1
