running 2.6.11-gentoo-r3
emerge of union-1.0.9 works fine
emerge =sys-fs/union-1.0.11 fails with error: `F_SETLK64' undeclared

Are you on the amd64?
Can you please post your full emerge info?

sorry, I have no experience in amd64-porting, since I dont own one. However I
would be happy to add a patch, when you find,hack up or already have one.

I fixed this a while ago on 64bit Xeon (Nocona) but forgot to commit the
patch... 2 files forget to include compat.h and thus FSETLK64 is undefined -
since the default FSETLK is 64bit wide on our arch. Tested again on my amd64,
and though I am quite sure the patch won't break 32bit - I leave it to the
maintainer to apply unconditionally.

InCVS, cheers.
