Via the comandline,

convert -trim

formerly (still works) convert -crop 0x0

Either will remove edges that are entirely the same color as the
corner pixels.

If PerlMagick doesn't have "trim" you should be able to use crop
with the 0x0 geometry.  Sorry, don't have docs handy right now.
You can get them from http://imagemagick.sf.net/docs/
