Compiling error

Hey.

Now that FLTK is up and working…this happens:

g++ -I/Applications/drag0n/drag0n.app/Contents/System/usr/local/include -I/Applications/drag0n/drag0n.app/Contents/System/usr/local/include/FL/images -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT -g -O2 -Wall -W -Wno-unused-parameter -fno-rtti -fno-exceptions  -L/usr/local/lib -o dillo dillo.o paths.o tipwin.o ui.o uicmd.o bw.o cookies.o auth.o md5.o digest.o colors.o misc.o history.o prefs.o prefsparser.o keys.o url.o bitvec.o klist.o chain.o utf8.o timeout.o dialog.o web.o nav.o cache.o decode.o dicache.o capi.o domain.o css.o cssparser.o styleengine.o plain.o html.o form.o table.o bookmark.o dns.o gif.o jpeg.o png.o imgbuf.o image.o menu.o dpiapi.o findbar.o xembed.o ../dlib/libDlib.a ../dpip/libDpip.a IO/libDiof.a ../dw/libDw-widgets.a ../dw/libDw-fltk.a ../dw/libDw-core.a ../lout/liblout.a -L/Applications/drag0n/drag0n.app/Contents/System/usr/local/lib -lfltk -lpthread -framework Cocoa -lz -liconv

/Applications/drag0n/drag0n.app/Contents/System includes a copy of my toolchain, also meaning FLTK and others.

What can I do to get rid of this duplicate error? From what I know, a function was declared twice somewhere, but then again I did not study the source code ^^.

Kind regards,
