What "hash" are you talking about?  sha1?  md5?  crc?

I *think* you are trying to say that gentoo has a tool to compute some
sort of hash for regular files in their source tree by:

	"gentoo's portage tree has manifests for each file"

but without knowing what kind of hash they use, I cannot tell you if you
can reuse some part of git to compute their hash without using their tools
(it also is unclear why you are not using their tool to compute their hash
and instead are expecting git to know about the specific hash function
used by them).

For exammple,

	"sha1sum Makefile"

would give you the SHA-1 checksum of the contents of the Makefile.  Is
that what gentoo's tools expect?  If that is the case, that is different
from the blob object name git will give to the contents of that Makefile,
so you cannot reuse much of git.
