Seems to be triggered by the combination of device-mapper and libzfs.
Created attachment 380370 [details, diff] Patch supplied upstream to fix library dependencies This bug is known upstream under #42392. The patch supplied there (and attached here) works as intended.
Additionally, the ebuild has to be modified to autoreconf the sources properly like in the revision 9999 ebuild.
+ 09 Sep 2014; Mike Gilbert <floppym@gentoo.org> + +files/grub-2.02_beta2-libzfs.patch, grub-2.02_beta2.ebuild: + Backport build fix for when both device-mapper and libzfs are enabled. Bug + 496608.
