Getting the latest Bluefish PHP IDE in Fedora 12 seems pretty simple and can be achieved in running several command lines.
sudo yum -y install gucharmap-devel pcre-devel aspell-devel enchant-devel
sudo rpmbuild --rebuild bluefish-2.0.0-4.fc12.src.rpm
sudo yum --nogpgcheck localinstall ~/rpmbuild/RPMS/x86_64/bluefish-2.0.0-4.fc12.x86_64.rpm
Personally, I am not a big fan of this sort of editors, but I am sure many developers switching from Windows to Linux will find it useful and accurate.
