Gentlemen: I have two computers, one with FC2 and one with FC3. There is a package called "fftw" which is one the FC3 system and I would like to get it installed on the FC2 system. Typing "yum info fftw" on the FC3 system returns Name: fftw, Version 2.1.5, Repo: fedora stable. Typing "yum info fftw" on the FC2 system returns "Cannot find a package matching fftw". Is there any way to move forward on the FC2 system short of changing it into an FC3 system? A corollary question is: "Given a working FC2 system, would I expect to be able to transparently do an FC3 installation on that system and still expect things like its ftp & http servers to still work?"
