dm_task_create is implemented in libdevmapper, the device-mapper library.
libdevmapper.c (the only suported backend) must be compiled in otherwise cryptsetup
will not work (there is no other backend implemented).

Please be sure you are using recent source code, old code allowed compilation
without libdevmapper library resulting in non-functional code.

See http://code.google.com/p/cryptsetup/source/checkout
