[magick-users] montage -label not working

[Dado Feigenblatt]

short story:
montage -label %f input.png output.png
works on old system but not on newer one. I get no label.

long story:
I have some very old scripts running on Red Hat 7.2 (yes, RH7.2) using 
montage version 5.4.7.
That is still working great for my needs, but I need to upgrade the 
system to FC4 or later.
While testing on an existing FC4 box with ImageMagick 6.2.2, I can't get 
-label to work.
I've tried playing with colors and fonts to no avail.
I used fonts listed by "xlsfonts" and then fonts listed by "convert 
-list type"

I tried the examples on http://www.imagemagick.org/Usage/text/

|convert -background lightblue -fill blue -font Candice -pointsize 72 label:Anthony label.gif
|

That complained about missing image label.gif
I've created label.gif and it still complained.
I've added an extra argument as the output image and all the command did 
(apparently) was to copy input to output.

Any idea what could be wrong?

Thanks,
