Read.... IM Examples, Basics

Well I am NOT suprised you get different results. You are doing things
IM v5 way, not the IM v6 way. What you are using is a legacy mode that is
depreciated, and has all the problems that IM v5 had. Specifically what
order should the operations be applied.
The -page in the above is useless, It only sets a 'canvas' size for PNG,
whcih normal PNG image files formats do not support!. Then you have two
resize operations in legacy mode. Which resize should be applied is
completely undefined.

Your command for BOTH v6 versions of IM should be...
convert -verbose -density 300 rotate.ps -resize 824x603 \
-shave 18x25 landscape.png
This should produce the same result.
See the link above, and in particular read the first section, about why
there was a command line change for IM v6, the section on 'legacy
support', and finally the example step-by-step IM command.
