Sven,

You might want to edit pct2rgb.py and change this line:

if format == 'GTiff':

to:

if format == 'GTiff' or format == 'HFA':

and see if that works.

Alternatively, get a GDAL build with BigTIFF support.  It would appear
you have either an old GDAL or a new GDAL with an old (pre libtiff4)
version of libtiff that does not support bigtiff.

Best regards,
