when I emerge tinyos, it hints !!! Digest verification failed: !!! /usr/local/tinyos-2-overlay/dev-tinyos/tos-sdk-c/ChangeLog !!! Reason: Filesize does not match recorded size !!! Got: 1141 !!! Expected: 936 Reproducible: Always Steps to Reproduce: 1. Just followed the steps in http://naurel.org/stuff/gentoo_howto_tinyos.html 2. Every thing is OK before Step 4 & 5: Install TinyOS 3. In the Step 4 & 5: Install TinyOS, at last step emerge tinyos the error occurs.
That is no official Gentoo-overlay so there's not much we can help you here. Maybe you can fix it by running "ebuild ... manifest" on that ebuild yourself.
