I have just installed the Mac OS X version 4.0.2 for PowerPC.  Everything installed fine, but I have encountered errors beginning when I run the script file.  When running the script, I get the following message:

Setting up environment for FreeSurfer/FS-FAST (and FSL)

FREESURFER_HOME /applications/freesurfer

FSFAST_HOME /applications/freesurfer/fsfast

FSF_OUTPUT_FORMAT nii

SUBJECTS_DIR   /applications/freesurfer/subjects

MNI_DIR   /applications/freesurfer/mni

It then goes back to prompt.  I was wondering why I was not receiving the following from the setup guide:

GSL_DIR         /usr/local/freesurfer/lib/gsl
FSL_DIR         /usr/local/freesurfer/fsl

I then tried the next step from the guide even though I did not receive the last two lines above.  When I tried to run tkmedit, from the freesurfer_home directory, on the bert orig.mgz file, I received this message:

GLUT: Fatal Error in tkmedit.bin: could not open display:

It then goes back to prompt.  This is where I stopped and wrote this email.  Any help would be great.  Thank you in advance.
