library (libdaq) version does not have something to do with the version
of some piece of software (daq). Sometime they are the same.

On some systems the package framework sets the library version to some
other version based on settings there, here for example:

$ ls -al /usr/local/lib/libdaq.so*
-rw-r--r--  1 root  bin  30282 Oct  4 14:46 /usr/local/lib/libdaq.so.2.1
$ pkg_info | grep daq
daq-2.0.6           data acquisition library for snort
