[Jscheme-user] Problems loading contributed scheme code+install stuff

A) These are in reverse order, but the transcript below is so long I thought this might get lost. After B) I tried getting the current codebase from CVS and building it. I'm sure this marks me as not being a true-believer, but wouldn't a Makefile or a build.xml be perhaps less exciting, but ultimately more useful ? Suffice to say I couldn't get it to build, though I got very close once I abandoned the default method and built an Eclipse project for it. build.CompilingLoadlet uses internal sun.* classes which apparently didn't make it to JDK 1.5, which is of course why you're not supposed to use them. There are also a lot of static method calls being made as if they weren't static, which is odd. B) When I try to load many of the files in the elf directory, I get the typical result below. Ideas?
