Answer 1

I had this problem and it turned out to be permissions.

sudo chown myuser:wheel /usr/local

then:

brew remove jpeg
brew remove imagemagick
brew install jpeg
brew install imagemagick

sorted it. Word of warning though: I had MySQL sittting in /usr/local/ too, and I inadvertently messed up permissions for that, so if you've got anything else important in there, be careful :-) Fixed that with:

sudo chown -R mysql:wheel /usr/local/mysql/data

Hope this helps someone!
