* Error: circular dependencies:

('ebuild', '/', 'sys-devel/gcc-4.4.4-r2', 'merge') depends on
  ('ebuild', '/', 'sys-libs/glibc-2.11.2', 'merge') (buildtime)
('ebuild', '/', 'sys-libs/glibc-2.11.2', 'merge') depends on
  ('ebuild', '/', 'sys-devel/gcc-4.4.4-r2', 'merge') (buildtime)

* Note that circular dependencies can often be avoided by temporarily
* disabling USE flags that trigger optional dependencies.

* IMPORTANT: 3 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.


我应该怎么做...
emerge -C 吗....

你看下sys-libs/glibc的ebuild就知道原因，方法了
sys-libs/glibc-2.10.1-r1.ebuild 里 依赖 DEPEND=">=sys-devel/gcc-3.4.4   
glibc-2.11.2.ebuild   DEPEND=">=sys-devel/gcc-3.4.4   但对x86             x86? ( >=sys-devel/gcc-4.3 )

而   sys-devel/gcc-4.4.4-r2   依赖是               elibc_glibc? ( >=sys-libs/glibc-2.8 )

所以 。万无一失的是   先升 到  sys-libs/glibc-2.10.1 ，再升gcc 到  gcc-4.4.4-r2。然后  glibc-2.11.2
如果想偷懒，则  --nodeps
或 改ebuild  欺骗portage   sys-devel/gcc-4.4.4-r2.ebuild  里  >=sys-libs/glibc-2.8  改成  >=sys-libs/glibc-2.6

话说回来，我已经够懶的了，你比我还-----  哈哈
