You might want to check the other components in the chain -- tiff2ps and ps2pdf 
-- to make sure that your version of libtiff is able to create the .tif file 
properly.

My suggestion is to:

1. Just receive the fax as a TIFF file, and see if you can open that up
2. If step 1 is okay, look at tiff2ps and make sure it's converting the TIFF 
file to postscript properly. Use ghostview or something like that to look at the 
output .ps file and make sure it opens up nicely
3. If step 2 is okay, look at ps2pdf and make sure it's converting the 
postscript file properly.

We had some similar issues, ended up removing the tiff2ps and ps2pdf from the 
processing and emailing the TIFF file directly to the recipient.

Cheers,
