One of our users (Nux) provides a small repository for RHEL 6. The repository is designed to coexist with Fedora’s EPEL repository. In order to add those repos to your system and install Shutter you can use the following commands:
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-1.el6.nux.noarch.rpm yum install shutter
Isso pode funcionar.
