[gentoo-catalyst] problem building installcd-stage2-minimal

Hi.  I am trying to build a installcd-stage2-minimal with some
modifications for zfs, which I found made by arantius@×××××.com..  I get
all the way through  compiling the kernel and then get the following
error:
Could not copy System.map from kerncache for the kernel package!
genkernel.log has no more information -- so how do I fix such a thing --
looks like the System.map is there in 
/var/tmp/catalyst/kerncache/default/livecd-stage2-amd64-20140808.zfs/gentoo/sources/System.map

Thanks in advance for any suggestions.
