RJAGS Installation Issues

The primary source of RPMS for JAGS is the repository created by Lars Vilhuber:
http://download.opensuse.org/repositories/home:/cornell_vrdc/

It is true that Lars does not create RPMs for Fedora, presumably because they do not use it at Cornell. I had not thought about this before. I do use Fedora but I always install JAGS from source.

It is quite easy to (re)build rpm binary packages on another platform
using the rpm source package. Usually the rpm source package is the
same for Fedora/CentOS/RHEL, unless you have some exotic dependencies.

Suse also offers a free build service (OBS) to do the building for
you. You upload a src rpm (or just give a hyperlink), and their
machines will build and publish binary rpm's for various distributions
and architectures of your choice, including Fedora. Thereby you can
easily manage your own repository, and your admin only has to add the
repository, and do a yum update once in a while.

Just for fun, I tried grabbing some src rpms from Lars' centos6 repo
[1] and build them for Fedora on OBS. I haven't tried installing them
(not a Fedora user), but all builds were successful so I'm going to
guess they will work. You can see the overview in [2] and grab
binaries from [3,4,5] for jags version 1,2 and 3, respectively.
