beginning to warm up in the world of redhat 8.0

the rpmbuild thingy worked great on my servers, after that i did the rpm -Uvh 
and that worked as well. but it only worked on my servers, i have the tn5250 
program their but i need it on this other linux machine. it gives me the 
"rpmbuild command not found", i figure its not installed. i'm trying to keep 
everything to a min on this machine, so i guess i need to copy the tn5250 files 
from my server to a floppy, then put the floppy in the other linux machine and 
copy it from the floppy to somewhere and try to run it. which files do i copy 
?? still wishing someone would just e-mail me the rpm's   p.s. thanks for the 
fast response on the last question. sorry to say, i'm just gettin started with 
the dumb questions.
