Buce  filed a deletion request for imgur-cli-svn :
I didn't spend much time trying to resurrect this package so maybe
there's a way to keep it. But the source doesn't seem to be available
via svn anymore and I couldn't readily find an alternate source via
google (despite several projects with a similar 'imgur-cli' name).
I seem to recall the tool erroring out the last few times I tried
using it as well, so I suspect that some changes on imgur's end made
this package incompatible with it.
