When I type: $> port dependents bzip2 I get the following: ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 ImageMagick depends on bzip2 Why all the repetitions? I only have one active copy of ImageMagick installed, and all inactive versions have been uninstalled: $> port installed | grep ImageMagick ImageMagick @6.3.2-9_0+darwin_8 (active) I can only assume that all these lines refer to previously installed, and since uninstalled, versions of ImageMagick. How does my system know about these previously uninstalled versions? I can't find any trace of the previously installed versions on my system. Is there some file somewhere that still keeps track of all the previous versions? Is there any way to update this file? Mark
