请教个emerge失败的问题。

gennewbie

昨天升级时发现n个包都报同一个错误：
libtool: compile: Failed to create `.libs'
make[2]: *** [gfile.lo] Error 1
make[2]: *** Waiting for unfinished jobs....
libtool: compile: Failed to create `.libs'
make[2]: *** [gmempp.lo] Error 1
libtool: compile: Failed to create `.libs'
make[2]: *** [GooHash.lo] Error 1
make[2]: Leaving directory `/var/tmp/portage/app-text/poppler-0.10.4/work/poppler-0.10.4/goo'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/var/tmp/portage/app-text/poppler-0.10.4/work/poppler-0.10.4'
make: *** [all] Error 2
看了看，我猜测可能是libtool有问题，于是打算从新emerge一下libtool，但是发现它也报错
Assembler messages:
Fatal error: can't create libltdl/.libs/libltdl_libltdl_la-lt__alloc.o: No such file or directory
make[2]: *** [libltdl/libltdl_libltdl_la-lt__alloc.lo] Error 1
make[2]: *** Waiting for unfinished jobs....
Assembler messages:
Fatal error: can't create libltdl/.libs/libltdl_libltdl_la-lt_dlloader.o: No such file or directory
Assembler messages:
Fatal error: can't create libltdl/loaders/.libs/libltdl_libltdl_la-preopen.o: No such file or directory
然后想也不想的就要从新emerge gcc。。。没想到它更离谱，报如下错误：
configure: creating ./config.status
mkdir: cannot create directory `conf4892.dir': File exists
config.status: creating Makefile
config.status: creating mkheaders.almost
config.status: creating config.h
make[2]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.3.3/work/build'
make[1]: *** [stage1-bubble] Error 2
make[1]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.3.3/work/build'
make: *** [bootstrap-lean] Error 2
我找到这个文件，删除了。从新emerge又报了一个类似的错误。删除所有临时文件，又从新下载了gcc的包，后还是不能解决。
我的emerge －－info如下：
