atlas does not recognize gcc49 gfortran

[Xsenon973@…]

Problem appears then I try to instal Atlas, xcode and xcode comand line tools installed. gfortran 4.9 installed too.But there is no string about F77 compiler. What do I make wrong??

xsenon$ which gfortran
/opt/local/bin/gfortran

But atlas can't detect this

atlas probably doesn't support gcc49 yet because gcc49 is still in development. Try gcc48 instead; that's the latest stable version.

Replying to ryandesign@…:

How can I downgrade gcc??

Nothing is wrong. The Portfile must be updated to take into account gcc4.9 and clang3.4. Will do that tomorrow. Thanks for reporting.

[Xsenon973@…]

what should i do tomorrow? simply repeat my effort?

[Xsenon973@…]

problem was solved by reinstalling gcc4.7 everything is OK thanks for advice

I am having similar troubles. I am running mavericks 10.9, trying to install atlas from macports. I first tried with gcc48 and left it for hours and didnt work. Then tried with gcc 47 and still took a couple hours with nothing. I cancelled and cleaned everything up but I dont know what to do. Seems like each time it also takes a lot of space on my computer that I can not recover. I heard mention of a bug with clang33.. how do I get clang34? wlll that fix it?
