Ok, I've tried another page:

    http://uml.devloop.org.uk/howto.html

Much more successful. Actually got the kernel (pre-built) to run in
UML mode. Couldn't get it to run right with their Debian-Wheezy
filesystem (got it to run, but lots of extra debugging info on
terminal), but worked great with their CentOS.

Then, I went to build perllinux to run on their kernel.

1) Term-Screen and Perl-Tidy are enumerated in the Makefile and import
lists with specific version numbers. I was able to find where they
were mentioned and fix this.

After I got those fixed, 'make get-required-imports' worked, but 'make
build-required' croaks with complaint about wrong kernel version.

I'll get back to it sometime, but just a bit too much trouble just now...
