Same error even if I've tryed that in the Makefile of libudns.a and
also in the Ruby extension Makefile. Same output as before (but now
with -DPIC):

gcc -I. -I/usr/include/ruby-1.9.1/x86_64-linux
-I/usr/include/ruby-1.9.1/ruby/backward -I/usr/include/ruby-1.9.1 -I.
 -fPIC -DPIC -fno-strict-aliasing -g -g -O2 -fPIC -DPIC -o em-udns.o
-c em-udns.c
gcc -shared -o em_udns_ext.so em-udns.o -L. -L/usr/lib -L.  -rdynamic
-Wl,-export-dynamic   -lruby-1.9.1 -ludns  -lpthread -lrt -ldl -lcrypt
-lm   -lc
/usr/bin/ld: ./libudns.a(udns_resolver.o): relocation R_X86_64_32
against `dns_defctx' can not be used when making a shared object;
recompile with -fPIC
./libudns.a: could not read symbols: Bad value

Thanks.
