`ppl7-config` returns libraries that arn't used

[jelu]

ppl7-config --libs returns a static list of libraries instead of the libraries it actually needs, in my case:

$ ppl7-config --libs
-L/usr/local/lib -lppl7 -lm -lresolv -lresolv -lresolv -lresolv -lresolv -lresolv -lresolv -pthread -L/usr/lib -lz -lbz2 -lpcre -lssl -lcrypto -lstdc++

libtool: link: g++ -I../../src -I../.. -g -O2 -I/usr/local/include -pthread -I/usr/local/include -pthread -o dnsmeter main.o  -L/usr/local/lib -lppl7 -lm -lresolv -L/usr/lib -lz -lbz2 -lpcre -lssl -lcrypto -lstdc++ -pthread
/usr/bin/ld: cannot find -lbz2
collect2: error: ld returned 1 exit status
Makefile:549: recipe for target 'dnsmeter' failed

Also -lresolv is specified 7 times for some reason.
