On a fresh Fedora 15 install, I was unable to install foreman from packages.

Here is the output from yum install :

--> Running transaction check
---> Package augeas-libs.i686 0:0.9.0-1.fc15 will be installed
---> Package foreman.noarch 0:0.4-0.1rc2 will be installed
--> Processing Dependency: rubygem(sqlite3-ruby) for package: foreman-0.4-0.1rc2.noarch
Package rubygem-sqlite3-ruby is obsoleted by rubygem-sqlite3, but obsoleting package does not provide for requirements
---> Package which.i686 0:2.20-2.fc15 will be installed
--> Finished Dependency Resolution
Error: Package: foreman-0.4-0.1rc2.noarch (foreman_test)
Requires: rubygem(sqlite3-ruby)
Available: rubygem-sqlite3-ruby-1.2.4-6.fc15.i686 (fedora)
rubygem(sqlite3-ruby) = 1.2.4-6.fc15

The workaround is to install dependancies as listed, install rubygem-sqlite3 package, then rpm -ivh --nodeps foreman*.rpm
