device-mapper

I am getting a blockage involving device mapper

[ebuild U ] sys-libs/e2fsprogs-libs-1.41.9 [1.41.3-r1] USE="nls" 485 kB [0]
[blocks B ] <sys-fs/e2fsprogs-1.41.8 ("<sys-fs/e2fsprogs-1.41.8" is blocking sys-libs/e2fsprogs-libs-1.41.9, sys-apps/util-linux-2.16.1)
[blocks B ] <sys-libs/e2fsprogs-libs-1.41.8 ("<sys-libs/e2fsprogs-libs-1.41.8" is blocking sys-apps/util-linux-2.16.1)
[blocks B ] sys-fs/device-mapper ("sys-fs/device-mapper" is blocking sys-fs/udev-146-r1)

I looked on bgo and found posts today involving this. They were
"resolved" by noting "device-mapper was merged upstream into lvm2.
Emerge a recent lvm2, it will automatically
unmerge old device-mapper."

I am not running lvm2 on this machine. I have device mapper because

sys-fs/cryptsetup-1.0.6-r2 pulled in by:
sys-apps/hal-0.5.12_rc1-r8

sys-fs/device-mapper-1.02.24-r1 pulled in by:
sys-fs/cryptsetup-1.0.6-r2

Does this mean I should emerge lvm2 even though this machine does not
use logical volumes?

thanks,
allan

The sys-fs/lvm2 package just contains utilities, it doesn't require
you to actually use LVM2. I also use it the same way as you. I now
have the lvm2 package and not device-mapper and everything still works
with my encrypted partition.

Thank you. It worked fine.
