Note that the I/O component of libtiff is pretty finicky. As the 
library was distributed (I got it about 8 years ago, I think) it 
used raw MacOS File Manager calls. The library as it is in my 
distribution (if I remember correctly) uses the Unix I/O file 
for libtiff and then uses either GUSI for unix-style 
open/close/read/write I/O or whatever MSL gives you. But for 
Python I did a workaround at some point to use stdio for I/O, 
because there were some problems with the other two I/O methods.

So to make a long story short: the first thing I would check is 
I/O. Maybe it's doing text I/O?

Hmm, thinking a bit further: every time my images show up with 
funny colors on the mac it turns out I haven't set foreground 
and background colors to white and black before doing the 
bitblit(), so that's also worth checking.
