Ciao, il problema e' che su Gentoo bisogna partire dai sorgenti. Bisogna scaricari i binari e compilare le librerie con i binari. Poi si compilano i sorgenti...
Ad un certo punto della compilazione il make si blocca:

make -C osprey/targx8664_x8664 BUILD_COMPILER=OSP

Al che m'e' venuto il dubbio: devo mettere USE="gfortran" e riemergere gcc 4.4.5?

Ciao
No, non centra nulla come hai potuto constatare.
Prova con "export MACHINE_TYPE=Amd64 ; make lib BUILD_COMPILER=OSP"
