[OS X TeX] Convert?

[David Arnold]

All,

After installing mactexlive 2009 sometime back, it seems "convert"  
doesn't work as it did.

david-arnolds-macbook-pro-2:temp darnold$ convert addition.tiff  
addition.jpg
convert: Compression algorithm does not support random access.  
`addition.tiff' @ tiff.c/TIFFErrors/323.

Should I just reinstall? Has it been fixed in the latest upload of  
mactex?
