unpleasant linker warning

When linking any binary (i.e. cabal) that uses the network package I get the following warning:

ld: warning: symbol `store' has differing types:
        (file /usr/lib/libnsl.so type=FUNC; file /home/pub-bkb/pc-solaris/ghc/ghc-6.12.1/lib/ghc-6.12.1/libHSrts_thr.a(Globals.thr_o) type=OBJT);
        /home/pub-bkb/pc-solaris/ghc/ghc-6.12.1/lib/ghc-6.12.1/libHSrts_thr.a(Globals.thr_o) definition taken

I've got network-2.2.1.7 that as extra-libraries: nsl socket
