[expert] SRPM installation?

[Dan Swartzendruber]

Is there a trick to installing source RPMs?  I 
downloaded  samba-2.0.5a-3mdk.src.rpm from one of the
mandrake mirrors, and installed it using 'rpm -ivh' (like all the binaries 
I do successfully).  When I then
query for the file list, I get told it isn't installed?

[root@sphinx local]# rpm -ivh samba-2.0.5a-3mdk.src.rpm
samba                       ##################################################
[root@sphinx local]# rpm -ql samba-2.0.5a-3mdk.src.rpm
package samba-2.0.5a-3mdk.src.rpm is not installed
