 I don't understand : do you have compiled db-4.2 with pthread ?

  1) yes : ruby must be compiled with pthread and you'll have the right
     flag 

  here an example with an old 1.8.1

svg% ruby -rrbconfig -e 'p Config::CONFIG["LIBS"]'
"-lpthread -ldl -lcrypt -lm "
svg% 

svg% cat src/mkmf.log 
have_library: checking for db_version() in -ldb-4.2... -------------------- yes

"gcc -o conftest -I/home/ts/local/rp/lib/ruby/1.8/i686-linux -I/home/ts/local/rp/lib/ruby/1.8/i686-linux -I/home/ts/local/db4.2.52/include  -g -O2 conftest.c  -L"/home/ts/local/rp/lib" -L"/home/ts/local/db4.2.52/lib"       -lruby-static -ldb-4.2  -lpthread -ldl -lcrypt -lm   -lc"
checked program was:
/* begin */

/*top*/
int main() { return 0; }
int t() { db_version(); return 0; }
/* end */

 2) no : you don't need to do nothing

svg% ruby -rrbconfig -e 'p Config::CONFIG["LIBS"]' 
"-ldl -lcrypt -lm "
svg% 

svg% cat src/mkmf.log 
have_library: checking for db_version() in -ldb-4.2... -------------------- yes

"gcc -o conftest -I/home/ts/ruby/db/bdb-0.5.1/src -I/home/ts/local/r182/lib/ruby/1.8/i686-linux -I/home/ts/local/db4.2.52/include  -g -O2 conftest.c  -L"/home/ts/local/db4.2.52/lib" -L"/home/ts/local/r182/lib"      -lruby-static -ldb-4.2  -ldl -lcrypt -lm   -lc"
checked program was:
/* begin */

/*top*/
int main() { return 0; }
int t() { db_version(); return 0; }
/* end */
