Along with the 1.6.18 and 1.7.4 SRPM toolkits, I've published an "svn2cl" SRPM packagong kit at:
https://github.com/nkadel/svn2cl-0.13-srpm This is because Subversion 1.7.4 discarded the "contrib" directory in the tarballs, and the svn2cl that was previously included was rather out of date. The RPM built from this "Requires:" subversion, but is independent of the version of Subversion, since this utility has its own versioning scheme. I'm also pushing this to Repoforge, but if you want svn2cl for subversion-1.7.x RHEL hosts, do feel free to use this.
