Matt,

I have no reason to believe this represents a bug in GDAL.

I would suggest you compile with the system libtiff as it is fairly
likely that mapnik depends on other libraries that also use libtiff
in which case mixing the internal GDAL libtiff and the system libtiff
could cause all sorts of problems.

Also, you need to do a "make clean" after a re-configure.  GDAL's makefiles
try to avoid unnecessary recompilation but in some cases it is at the cost
of not forcing rebuild of stuff that ought to have been recompiled (for
instance after reconfiguring).

If the problem persists you would pretty much need to track it
down in gdb, or perhaps with valgrind.  Pay particular attention to the
possibility of more than one libtiff ending up in the final process.

Best regards,
