This looks like it to me.  Let me know if you need more.

configure:22441: checking for dm_task_set_name in -ldevmapper
configure:22471: gcc -o conftest -O2 -g -pipe -march=i386 -mcpu=i686

Also, I note from another sequence in this thread:

Could your older version of device-mapper be the problem?  I'm also
running the current 1.00.14-1.0.

When I couldn't get cryptsetup to compile, I downloaded your binary
package and followed the directions on your web page.  Went OK until the
losetup:

  [root at hazard1 local]# losetup /dev/loop0 /tmp/test.img
  /tmp/test.img: No such file or directory

So, recalling advice from elsewhere:

  [root at hazard1 local]# dd if=/dev/urandom of=/tmp/test.img bs=1M count=4
  4+0 records in
  4+0 records out
  [root at hazard1 local]# losetup /dev/loop0 /tmp/test.img
  [root at hazard1 local]# cryptsetup create test /dev/loop0
  Enter passphrase:
  cryptsetup: error while loading shared libraries: /lib/libdevmapper.so.1.00: undefined symbol: is_selinux_enabled
  [root at hazard1 local]#

Seems to support the theory that the device-mapper version may be
problematic.  Stuck again. :-(
