Problem with Macports on OS X 10.8

[H.-Ulrich (Uli) Wienands]

I am trying to install octave on a Mac Pro running 10.8.(latest). I have 
Xcode 5.1.1 installed.

A bunch of deps is installed successfully but then it chokes.

I finally track this down to an inability to install any compilers (? 
that is what it appears to be).

Trying to build up from the bottom I install llvm 3.4, 3.5 etc. Works ok 
until I hit llvm-3.9. It appears llvm-3.
9 has itsels in its list of dependencies.

I made sure my Macports installaion was up-to-date (I installed it only 
a couple of weeks ago but still I updated everything) and tried to clean 
whatever would not install. No joy.

Here is the tail from the log of my atttempt to install llvm-3.9. Note 
that none of the clangs would install. And I never get an error message 
beyond "Installatino of ..." has failed. I also tried installing gcc46 
(which I have installed even on a fairly ancient on a 10.5 PPC system, 
no joy either.

Any hint would be appreciated.
