nsl=name service library. All of it's functions are in FreeBSD implement in 
libc. If this mod_dispatcher.so is indeed loadable by FreeBSD's linker, then 
you can provide a dummy libnsl.so.1, like so:

$ cat <'EOF' >BSDmakefile
SHLIB=nsl
SHLIB_MAJOR=1
NO_MAN=yes
SRCS=nsl.c

.include <bsd.lib.mk>
EOF
$ cat <'EOF' >nsl.c
int nsl_dummy(void);

int nsl_dummy(void) { return 0; }
EOF

$ make; sudo make LIBDIR=/usr/local/lib install

The symbols it's looking for should be provided by libc, but if there's any 
undefined ones, this trickery gets a little dangerous and you're better off 
asking the developers for a native FreeBSD version.
