side effects of installing gimp

[Mark Copper <mcopper@titaninterface.com>]

Hi,

I want to install gimp on an out-of-the-box installation of etch with
Gnome on an AMD64 system.

#aptitude install gimp

says 3 packages will be installed (gimp gimp-gnomevfs and gimp-python),
but that 91(!) packages will be removed.  These include compilers
(binutils, cpp, gcc, guile, python2.4), possibly some duplication
(cupsys-common, gs-common), and many lib packages.

Is there something wrong with this picture?  Is installation safe?
*Why* would it be necessary to remove so many packages?

Thanks.

Mark
