Could it be that you have built a world with option WITH_BIND_LIBS=yes 
or installed dns stuff from ports?

I had also problems with PHP and undefined references to these functions 
because FreeBSD does not install the header files which belong to the 
libraries if you use WITH_BIND_LIBS=yes, i.e. the definitions

   #define res_ninit       __res_ninit
   #define res_nmkquery    __res_nmkquery
   #define res_nsend       __res_nsend
   #define res_nclose      __res_nclose

and others are missing. You can solve the problem if you prepend "__" to 
these functions in the PHP source code. I attached a patch to this mail. 
Put it into /usr/ports/lang/php5/files, 'make clean' and install PHP again.

The PHP project don't feel responsible for their non-working and 
ignorant configure script.
