After making some progress cleaning up the machine room I naturally had to fiddle with a couple of the machines therein. The good news is that they're going again when I thought they had been having problems. I think it was simply that one CD drive is not something that can be booted from.
I recalled needing DOS or Windows 3.x for something and so set up my first dual-boot (maybe more than dual, but that'll be later) machine. A small partition for DOS and WfW 3.11 and a larger partition for DeLi Linux. After whacking DeLi into shape (sshd needs to have stuff aimed right, su needs to have the right permissions, suauth needs to exist...) I got to adding the newest version of rhapsody - which promptly failed to compile.
Turns out the developer has been using ncurses 5.4 rather than 5.0 as listed on the rhapsody web site. So I grabbed ncurses 5.4 and compiled it. This takes quite a while on a Pentium 90. A. Long. While. That's just ncurses. I now realize I don't have the patience for a gentoo install save perhaps on damnfast hardware. However, after that compile and install, rhapsody did compile and install.
