can't selfupdate, can't install invalid command name "license"

[Uwe Brauer]

Hello

I  just downloaded the last darwin port (1.7) for Leopard. Now 2 
problems occur

sudo port -d selfupdate

gives me
"macports::selfupdate [array get global_options]"
Error: /opt/local/bin/port: port selfupdate failed: Error installing new
MacPorts base: shell command "cd
/opt/local/var/macports/sources/rsync.macports.org/release/base &&
./configure --prefix=/opt/local --with-tclpackage=/Library/Tcl
--with-install-user=root --with-install-group=admin
--with-directory-mode=0755 && make && make install" returned error 1
configure: error: in
`/opt/local/var/macports/sources/rsync.macports.org/release/base':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.


and when I try to install say xemacs
sudo port install xemacs

I obtain
Error: Unable to execute port: invalid command name "license"

So I thought the reason lies in the missing CC compiler
sudo port install apple-gcc40

gives

Error: Unable to open port: invalid command name "livecheck.type"



what can I do

thanks very much
