That's true, but bitmap() is failing in its check of the available 
types.

As so very often, we lack the 'at a minimum' information requested in 
the posting guide.   Run the equivalent on your OS of 'gs -help' to 
see what is going on: the problem result from bitmap() being unable to 
parse the output of that command.   Probably the ghostscript 
installation is broken, but it could just be that this is a version 
that we've not seen before.
