[TYPO3-debian] Typo3 can't find graphicsmagick

> Make sure imagemagick package is uninstalled clearly.

With aptitude search i find following packets:

galadriel:/opt# aptitude search imagemagick
p   imagemagick                                        - Image manipulation 
programs
v   imagemagick-dev                                    -
v   imagemagick-doc                                    -
p   imagemagick-typo3-4.2.9                            - Image manipulation 
programs.

I think 'p' means not installed, right? what does it means v. I can't find 
any solution in the man pages.
I can't delete 'imagemagick-dev' with apt-get remove imagemagick-dev
