Hi Marc,
Checked out revision 4892.
Oh the instructions are out of date and point at the old v3(?) repo.
svn://coreboot.org/coreboot/trunk/payloads/libpayload
You are right about the old version. I send a patch to update the readme.
Unfortunately the updated repo r6468 gives exactly the same error output on my computer.
More suggestions?
Thanks, Nils.
