Yes, but I the simple minded user that I am turned it on without reading
the Kconfig help carefully.  Now, it's off, and it compiles.

But, now for more interesting stuff:

[root@spc1 steven]# cd /
[root@spc1 /]# mkdir share_r4
[root@spc1 /]# mount -t reiser4 /dev/hda11 /share_r4
[root@spc1 /]# df -T

I have recently run mkfs.reiser4 on /dev/hda11 with no options.
The reiser4progs version is 0.4.12.

I made a local clone of the 2.6-test bk tree on the new reiser4
file system and that worked OK.

I then did a "time bk -r check -acv", twice for both reiser4 and ext3.
Here are the results for the second run for each (I neglected to
preserve the results for the initial bk -r check -acv):

Reiser4:
real    1m27.774s
user    0m33.685s
sys     0m16.059s

Ext3:
real    2m55.179s
user    0m32.752s
sys     0m5.835s

Nice work.  I'll try to break Reiser4 now.
