[gentoo-dev] portage error

[Urashima]

Even when I run a emerge --pretend xfree as the portage faq says.. I get a weird error like..
Calculating dependencies \Traceback (most recent call last):
  File "/usr/bin/emerge", line 1236, in ?
    if not mydepgraph.create(mytype+" "+portage.root+" "+mykey,None,"--onlydeps" not in myopts):
  File "/usr/bin/emerge", line 410, in create
    edepend=eval(mydb.readline())
TypeError: expected string without null bytes

I get errors like this with bitchx from portage too..

Thanks.. =)
