CentOS - Apr 2012 - imagemagick convert/display eps file no decode delegate

I am finding on all my CentOS 5.8 systems (all fully updated but a variety of
package mixes) that the display or convert commands from ImageMagick are unable
to handle eps files. I get  error output as follows, curious if anyone else sees
this

$ convert rna.eps rna.epi
convert rna.eps rna.epi

ImageMagick 5.2.8.0-12.el5
ghostcript-8.0-14.el5

the equivalent GraphicsMagick command
gm convert

does work

This is a recent development, but I can't say how recent
