buggy postscript?

[Helge Avlesen <avle@xxxxxxxxx>]

Dear Ferreters,
I am trying to plot this file
http://www.ii.uib.no/~avle/meta-bugged.plt   (1MB...)

doing a 

yes? sp gksm2ps -R -p portrait -l cps -o storm.ps metafile.plt
greadgksm()  162 No item is left in GKS Metafile input

goes ok, except from the no items left message that has not hurt
before.

viewing the ps file in gv gives almost all of the image except the white
labels spotted e.g. here http://www.ii.uib.no/~avle/ormen/100mabfiles/pic9.gif
and this error message:

also fail reading the file.  is it possible to work around this, so I
can get my white labels into a valid ps file?  ferret script to
generate picture appended below
