rpm -i does nothing

[John V. Pope]

FC1 Gurus:

I am attempting to install the kernel source on my server as the first step
toward recompiling a USB driver.  When I issue the rpm command, nothing
happens and the shell prompt returns within a few seconds.  No output is
generated and no files are installed.  I have tried this on two different
FC1 servers with identical results.

Here's my shell session:
# rpm --checksig kernel-2.4.22-1.2149.nptl.src.rpm
kernel-2.4.22-1.2149.nptl.src.rpm: (sha1) dsa sha1 md5 gpg OK
# rpm -i kernel-2.4.22-1.2149.nptl.src.rpm

What am I missing?  This used to work for RH9.

Thanks,
John V. Pope
