plruby 0.3.9, ruby 1.8.1 (using Ian's binary RPM).

$ ruby -v extconf.rb --with-pgsql-include=/usr/include/pgsql
ruby 1.8.1 (2004-01-01) [i686-linux-gnu]
checking for ruby_init() in -lruby-static... yes
checking for catalog/pg_proc.h... yes
checking for PQsetdbLogin() in -lpq... yes

creating Makefile

  ========================================================================
  After the installation use something like this to create the language
  plruby


    create function plruby_call_handler() returns language_handler
    as '/usr/lib/ruby/site_ruby/1.8/i686-linux-gnu/plruby.so'
    language 'C';

    create trusted  language 'plruby'
    handler plruby_call_handler
    lancompiler 'PL/Ruby';

$ ldd src/plruby.so | grep ruby

$ du -b src/plruby.so
233472  src/plruby.so



If I create with -lruby-static (no -lruby):

$ ldd src/plruby.so | grep ruby
$ du -b src/plruby.so
1904640 src/plruby.so


If I use a static ruby (ruby configured with --disable-shared), I can't 
get the resulting plruby.so to work (no ruby runtime linked).

Thanks,
