Bug: Ruby 1.9.0 installs executable into wrong place

At least I think this is a bug. Since I get a "404 not found" when
calling <http://www.ruby-lang.org/cgi-bin/ruby-bugs>, I'm not doing a cc
to ruby-bugs@ruby-lang.org.

I've downloaded the development version of ruby; this is how I tried to
install it:

DID:
    wget ftp://ftp.ruby-lang.org/pub/ruby/snapshot.tar.gz
    tar xzf snapshot.tar.gz
    cd ruby
    ./configure
    make
    checkinstall

EXPECTED:
    The Debian package generated by checkinstall (which uses `make
    install`) contains a file called /usr/local/bin/ruby1.9.

GOT:
    A file /usr/bin/ruby1.6. All other files seem to be in the right
    place (under /usr/local).

SYSTEM DETAILS:
    Linux 2.4.22-1-k6 #5 i686 GNU/Linux.
    Ruby 1.6 and 1.8 installed from Debian packages.
    gcc version 3.3.3 (Debian 20040422).
