hi again guys

omg i'm an idiot. i hadn't fully installed xquartz, sorry. i may have also messed up some path stuff last night as i tried to troubleshoot, so i'm still getting an error about DYLD_LIBRARY_PATH but overall it's looking better. first i'll paste my current output of afni_system_check, and then at the bottom of this message i'll respond to rick's newest inquiry:

========================= summary, please fix: =========================
* AFNI programs show FAILURE
* insufficient data for AFNI bootcamp
* OS X version might be old
* consider setting DYLD_LIBRARY_PATH to /opt/X11/lib/flat_namespace
