Problems installing denemo

[Hubert Spall - Tamarin Design Ltd.]

I am trying to install denemo, I have all the dependencies installed,  
but I get errors when it comes to install denemo:


--->  Building denemo with target all

I'm afraid I don't really know what much of that means, but I'm  
running 10.4.9 on intel macbook if that makes any difference, and  
macports is all up-to-date and working for other installations. Any  
help would be appreciated.
