i've been trying to install xmms, at the same time its my first time using the command line...i've learnt that there is no setup launcher as in windows and the following command line must be typed, people have told me 2 type with small variations ( one has "i" and one has "ivh") i've tried both and neither work...giving me the following error:

[root@localhost ~]# rpm -i xmms-1.2.10-1.src.rpm
error: cannot create %sourcedir /usr/src/redhat/SOURCES

[root@localhost ~]# rpm -ivh xmms-1.2.10-1.src.rpm
error: cannot create %sourcedir /usr/src/redhat/SOURCES

You need the non-src rpm, otherwise you'll have to compile it first...
Also, try researching/using the apt-get or yum install tools as they will handle rpm dependencies automatically for you.
