Version numbers of Fedora Core 3 programs

[Don]

Hi,
 
Newly installed Fedora Core 3 box.
 
Previously (Fedora 2,1 and RedHat), I could get application version numbers
(e.g. httpd, squid, etc...) by typing at the command prompt:
 
appname -v
 
With my fedora core 3, this just returns the command prompt with no output.
Has something changed?  How can I get the version numbers of all my
installed application severs?
 
Thanks,
Don
