Hi,
Attached patch fixes a typo in configure.in of device-mapper.
As a result of the typo, DMEVENTD_PATH in libdevmapper-event
could be set ignoring "exec_prefix" and the monitoring may not
work.
For example, LVM2 may complain it can't communicate with dmeventd:
# lvm.static lvcreate -m1 -l1 testvg
Unable to read from event server.
Unable to read from event server.
testvg-lvol0: event registration failed: Input/output error
testvg/lvol0: mirror segment monitoring function failed.
Logical volume "lvol0" created
while in the background, dmeventd caused segfault soon after startup:
>From syslog:
dmeventd[688]: dmeventd ready for processing.
kernel: dmeventd[688]: segfault at 08000000 eip 4ff615a7 esp bfafe2f8 error 4
Thanks,

Fix a typo in configure.in ("dmeventd_pref" should be "dmeventd_prefix")
As a result of this typo, LVM2 commands might try to invoke dmeventd
which doesn't match to the library version and monitoring fails to work.
