Subject: [ruby-core:18805] 1.9.0-4 "make test" fails under Ubuntu Dapper

Building ruby-1.9.0-4 on Ubuntu Dapper (6.06), I get the following error:

$ ./configure && make && make test

It looks like 'make test' is using the ruby already installed in the system,
rather than the ruby-1.9.0 that it has just built.

Notice that the path of the offending file is /usr/lib/ruby...
and also that this is a known problem with ruby-1.8.4:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/171532

Ubuntu Dapper has ruby 1.8.4 in its base system.

ii  ruby1.8                                1.8.4-1ubuntu1.5                Interpreter of object-oriented scripting lan

$ ruby -v
ruby 1.8.4 (2005-12-24) [i486-linux]

ISTM that 'make test' ought to be using the ruby it has just built, not any
other version installed on the system.

The build instructions in README say that if you want to run 'make test',
you can do this *before* 'make install'.

Brian.
