The file nfs-utils-0.3.3-gentoo.diff is missing from the files directory, yet the ebuild for 0.3.3 contains a patch statement for it. The package compiles ok, but a file not found message is issued during compilation. As this is a minor patch (to include time.h in rpcmisc.c) and hasnt changed in previous versions, I simply copied the previous 0.3.1 patch, though I have no idea if this patch is still required or not. Just a minor fix, I guess
Thanks for the catch Todd!
nfs-utils-0.3.3-r1 is out and no longer includes the patch, so the issue goes away. I guess this bug can be closed.
