Hello,

I've used FreeSurfer previously on a linux machine (from a previous lab). Now, I have just installed it on a Mac OSX, using the "freesurfer-Darwin-lion-stable-pub-v5.3.0.dmg" version. I followed all the instructions on the installation page. However, there were segfault errors when running both tkmedit and tksurfer as follows:

Any idea what went wrong and how to fix it?

Thank you!
