[gentoo-user] Cloned partition won't emerge some packages

[Mick]

I used:

 tar -X file.list -lcvSf - . | (cd /new_gentoo_partition; tar -xpvf - )

to clone a gentoo / partition to another partition on the same disk (I
want to run some tests from it).

The file.list has this is in it:

tmp/*
proc/*
sys/*
dev/*
etc/mtab
usr/portage/distfiles/*


However, I can't emerge some packages from it like gcc or subversion ...

This is what gcc shows:

=============================

I don't understand what this is about:  "configure: error: C
preprocessor "/lib/cpp" fails sanity check"

I attach the config.log which has some errors in it.

Have you come across anything like this in your travels?

I don't really know what's wrong with the cloned system or how to fix it. :-(
