hi, it seems obvious to me, but whenever i am missing a program like startx, xterm, rgrep, libXpm, etc i just grep the Contents file:
<download Contents-i386.gz> (or whatever for your architecture) this is in dists/slink/ zgrep xterm Contents-i386.gz | less if you get HEAPS of results, narrow it down with zgrep xterm Contents-i386.gz | grep bin | less and there will be the package name, no stress. Paul
