replacing pkg_install fails on DragonFly 4.3-DEVELOPMENT with

This may be some of the feared clash of symbols as discussed earlier on the mailing lists.  DragonFly 4.3-DEVELOPMENT has libbz2 in base:

$ ls -la /usr/lib | grep bz2
-r--r--r--  1 root  wheel    285858 Sep  1 15:01 libbz2.a
lrwxr-xr-x  1 root  wheel        11 Sep  1 15:01 libbz2.so -> libbz2.so.2
