Hello,

Both polybori-0.6.4-r1 and polybori-0.6.5 fail to build here on amd64 for the  
same reason. The important snippet is:

rm: cannot remove  
`/var/tmp/portage/sci-mathematics/polybori-0.6.4-r1/image//usr/lib64/lib*.so*':  
No such file or directory
  * ERROR: sci-mathematics/polybori-0.6.4-r1 failed:
  *   failed to remove shared objects
  *
  * Call stack:
  *     ebuild.sh, line  54:  Called src_install
  *   environment, line 5124:  Called die
  * The specific snippet of code:
  *       rm "${ED}"/usr/$(get_libdir)/lib*.so* || die "failed to remove  
shared objects"
  *

Under the /image directory polybori installs the libs under /usr/lib instead  
of /usr/lib64. This seemed to be an issue previously with polybori.
