The 1.6.5 version of git will include (and rc already does) a new, faster SHA1 implementation (can be build by setting BLK_SHA1 environment variable). Moreover because of that the Mozilla SHA1 was removed from git (http://git.kernel.org/?p=git/git.git;a=commit;h=30ae47b4cc19dce42f51b4fa378d315a71b08957). So the ebuilds for the release candidates and final 1.6.5 version should not include mozsha1 USE flag anymore and maybe introduce the blksha1 flag instead. Reproducible: Always
Created attachment 204353 [details, diff] simple patch for the ebuild Patch introduces a new USE flag blksha1 and removes the mozsha1 one. Also, I guess it is not necessary to depend on openssl if the blksha1 is used.
Added to 1.6.5_rc2 and 9999.
