  I won't comment on that one ;-)...

 [ these warnings are normal for ./HOME_INSTALL, just some old make
limitation (or my limitation, I'm unsure now) ]

  Unless I am very much mistaken here, you have a broken rbconfig.rb
file (the file where Ruby stores its various compilation options).
Please find it (it should be something like
/usr/(local?)/lib/ruby/1.8/x86_64-linux/rbconfig.rb), and edit the
line containing

CONFIG["CFLAGS"] = "something"

  to add -fPIC (see http://tioga.rubyforge.org/FAQ.html, under
Compile-time relocations errors, it probably is the same problem). For
the record, the -fPIC compiler option forces the compiler to produce
code suitable for dynamic linking (necessary for ruby extensions).

  I'm unfamiliar with the way TeX Live presents itself on the
installation CD, but you definitely don't need the full TeX Live
distribution to run Tioga. For information, the Debian package needed
is texlive-latex-base, maybe that will help you finding what you need
there.

  Please tell us if that can get you any further !

  Cheers,
