Thanks so much, Ptylor. But the same error shows up again, after I have installed "GSL" in my mac.
usr/local/bin/gcc -O2 -DDARWIN -m64 -Wcomment -Wformat -DUSE_TRACING -DHAVE_XDBE -UDONT_USE_MCW_MALLOC -I. -I/usr/local/afniX/include -I/usr/local/include -I/usr/X11R6/include -I/sw/include -I/usr/local/include -I../nifti/nifti2 -I../nifti/niftilib -I../nifti/nifticdf -I../nifti/znzlib -I../3DEdge/src -I../rickr -I../ -I../niml/ -Igts/src -I../SUMA/ -c DoTrackit.c
DoTrackit.c:9:29:

make[1]: *** [DoTrackit.o] Error 1

Do you have any clue on this?
Thanks,
