Thanks hitachi303,

The lack of checksum verification and some had argued also a comparison 
between two different mirrors, is an identified security weakness of Gentoo 
since its early days.  I remember a mirror had been compromised in the early 
2000s and people had to rebuild their systems.

I would rather not disable portage verification, but fix what's wrong with one 
PC.
