Anyone running giFTui successfully on CentOS?

Oh... I thought rebuilding RPMs involved a lot of programming knowledge 
or something. Lord knows configuring and making binaries is tricky, at 
least for a newbie.
Does that pattern you've written above apply for most package rebuilds?

Hey, thanks! That's really cool of you.

But, as is often the case with my Linux experience, I'm on to the next 
error:

[dave@localhost ~]$ giftui
giftui : No host to connect /apps/giftui/daemon/host.
*** glibc detected *** double free or corruption (fasttop): 0x089f4448 ***
Aborted

Perhaps giFTui is just too beta to be used by me.
Anyone recommend a good peer to peer software for all the non-bittorrent 
networks, like gnutella and eDonkey?
