Its a single source rpm for all Redhat-based distributions, so you should be able to do:
rpmbuild --rebuild graphviz-2.14.1-1.src.rpm
[ernst] I typed "rpmbuild --rebuild graphviz-2.14.1-1.fc8.i386.rpm
Error: source package expected, binary found Error: graphviz-2.14.1-1.fc8.i386.rpm Cannot be installed
[ellson] Use the .src.rpm
[ernst] Thanks, that worked foer the build. I have rebuilt. I went to:
/usr/src/redhat/RPMS/i386 and typed "rpm --install graphviz-2.14.1-1.-i386.rpm"
And got a bunch of messages to the effect of:
"File xxx from install of 2.14.1-1 conflicts with file from package 2.8-1"
[ellson] Either uninstall graphviz-2.8 before installing graphviz-2.14.1:
rpm -e `rpm -qa | grep graphviz` rpm -ivh graphviz*rpm
or upgrade the rpms instead of installing:
rpm -Uvh graphviz*rpm
