Comment 5 for bug 814280

Can you please run hugin again and generate the error again.
After the error please open a terminal and type "tail -50 /var/log/system.log > systemlog.txt".
This will copy the last 50 lines into the file systemlog.txt. This will will be in your home folder. I assume 50 lines are far too much, but please check if it contains gnumake info.
Could you please attach that file to this bug ticket.

Another issue could be that enblend is not compatible with Lion. gnumake calls enblend and because enblend fails, it issues an error back to gnumake. gnumake is also used in earlier stages of the process and it doesn't fail there.
So could you again switch to a terminal and type "/Applications/Hugin.app/Contents/MacOS/enblend -v --version".
This will simply show you some info about enblend or enblend might crash.
