Thanks Christopher,

now the issues with 4.7.2_alpha1 and masking disappeared, I came three  
packages further. Now the filesize of  
/usr/portage_caiman/distfiles/elldata.tgz does not match recorded size:

>>> Emerging (4 of 17) sci-mathematics/pari-2.4.3-r1 from sage-on-gentoo
  * pari-2.4.3.alpha.tar.gz RMD160 SHA1 SHA256 size ;-) ...
