Sorry for the exceedingly short answer.
The problem is caused by some recent modifications in the ruby_1_8 branch
(also in HEAD). That was fixed on Nov 25, so if you get & compile a
recent stable-snapshot RubyGems will work fine. You need not switch to
1.9 for that.

You can also apply the patch I posted under
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/121702
to RubyGems' sources. That should fix the RubyGems issue you're
experiencing, regardless of the ruby version you use.

If you want to build your own Debian package corresponding to the latest
stable version from CVS, fetch the tarball,  apt-get source ruby1.8,
and place it under ruby1.8-1.8.1+1.8.2pre2/ with a suitable name. 
You'll have to remove several patches from debian/patches (they have
already been applied to that codebase). Then run   fakeroot debian/rules
to create the binary packages.

If you want to overwrite the files managed by Debian (not a good idea),
just set the --prefix explicitly when running ./configure instead of
editing config.h. The settings used by Debian are (slightly edited):

./configure \
 --prefix='/usr' \
 --datadir='/usr/share' \
 --mandir='/usr/share/man' \
 --sysconfdir='/etc' \
 --localstatedir='/var' \
 --with-sitedir='/usr/local/lib/site_ruby' \
 --with-default-kcode=none \
 --with-dbm-type=gdbm_compat \
 --with-tklib=tk8.4 \
 --with-tcllib=tcl8.4 \
 --with-tcl-include=/usr/include/tcl8.4 \
 --with-bundled-sha1 \
 --with-bundled-md5 \
 --with-bundled-rmd160 \
 --enable-pthread \
 --enable-shared \
 --enable-ipv6 \
 --with-lookup-order-hack=INET

Hope this helps.
