Once you unpack the source rpm (rpm -Uvh xx.src.rpm) you can just
rebuild by "cd /usr/src/redhat/SPECS" and "rpm -ba

So the question is: why do you need to rebuild it?

If you need to change kernel options and want to get an modified rpm
back then you need to (this is from memory):

- rpm -Uvh kernel-2.4.19-1.ll.src.rpm
- cd /usr/src/redhat/SPECS
- rpm -bp kernel-2.4.19-1.ll.spec (prepares the source, does not build)
- cd /usr/src/redhat/BUILD/kernel-2.4.19/linux-2.4.19/

At this point the configuration files are stored in configs/, so choose
one (i386, i686, etc) and "cp configs/kernel-2.4.19-i586.config
.config". Run make xconfig, change options, save and copy the
configuration back to /usr/src/redhat/SOURCES, such as "cp .config
/usr/src/redhat/SOURCES/kernel-2.4.19-i586.config". After that you
should be able to rebuild the source rpm and get what you want (but it
would also be nice to change the release number of the package).

Well, maybe 2.4.19 does not like gcc3.2, I have not tried that
