emerge system failed while building python

[longint]

After installing from stage1_1.4b and doing a emerge system i got errors while
building python regarding _hostshot (and _weakref ?):

<some compiling stuff, not bad looking>
WARNING: removing "_hotshot" since importing it failed
skipping 'weakref' extension (up-to-date)
WARNING: removing "_weakref" since importing it failed
error: build/temp.linux-i686-2.2/hotshot.o: No such file or directory
make: *** [sharemods] Error 1

Any ideas? TiA
