Thanks Anthony for the help.  Still is not working though.

the original problem:

% convert thumbnail.gif -border 2 -alpha transparent \
-background none -fill white -stroke none -strokewidth 0 \
-draw "@rounded_corner.mvg" rounded_corner_mask.png
convert: UnrecognizedAlphaChannelType `transparent'.

the workaround:

-alpha transparent basically takes an existing image and turns it
transparent.  For older versions the equivalent is
    -matte -channel A -evaluate set 0 +channel

so i tried the substitution:

convert thumbnail.gif -border 2 -matte -channel A -evaluate set 0 +channel \
          -background none -fill white -stroke none -strokewidth 0 \
          -draw "@rounded_corner.mvg"    rounded_corner_mask.png

which unfortunately returns:

    convert: error while loading shared libraries: libMagickCore.so.2: 
cannot open shared object file: No such file or directory

googling the error i found a page that talks about installation on 
Ubuntu and the error.  Says to add the following line to ~/.bashrc:

|   export LD_LIBRARY_PATH=/usr/local/lib|

Sorry I am a dabbler, not a s/a type, what is the equivalent in .csh or 
.zcsh? Or what next as this is looking like an install/environment 
problem to me?

-Bob
