graphicsmagick-libmagick-dev-compat both conflicts with and replaces libmagick9-dev, you can't install both at the same time.
Was that during an upgrade to hardy?

[h_a_w_k (h-a-w-k)]

no, it was during instaling libmagick9-dev. It seems that apt-get wasn't aware of conflict until it actually tried to replace the file.

[Cesare Tirabassi (norsetto)]

Yes, apt-get and aptitude do not handle conflict resolutions very well.
Can you try to see if synaptics or adept are capable of resolving the conflict?
At least installing graphicsmagick-libmagick-dev-compat over libmagick9-dev should be handled more gracefully.

[h_a_w_k (h-a-w-k)]

synaptic also produces error while installing one of those packages when the second is already there.

[Nelson A. de Oliveira (naoliv)]

It's not a problem with apt-get nor with aptitude.
We have fixed this bug on Debian with graphicsmagick version 1.1.11-2:

   * debian/control: ImageMagick's -dev packages have stopped providing
     virtual, unversioned aliases, recently. Add explicit Conflicts and
     Replaces on the versioned package names libmagick9-dev and
     libmagick++9-dev in the -compat-dev package. Closes: #476584

[Cesare Tirabassi (norsetto)]

Ah yes, I was looking at the intrepid version, so problem solved.
