[CentOS] ghostscript 8.64 errors.

Hello,

To fix some issues in working with gs 8.63 I had to upgrade to 8.64. I build the rpm from ghostscript-8.64-9.fc11.src.rpm. I get the following error when running 

gs -q -dSAFER -dNOPAUSE -dBATCH -dUseCropBox -dFirstPage=1 -dLastPage=1 -sOutputFile=/tmp/TIFF-%d.tif -r300 -sDEVICE=tiff12nc foobar.pdf

GPL Ghostscript 8.64: Unrecoverable error, exit code 1

I am kind of at loss what fonts are missing. I had 8.63 installed and I did a rpm -U --force. I would appreciate recommendations on fixing this problem.

thanks
john
