rcairo is a Ruby bindings for cairo(*).

  Cairo is a 2D graphics library with support for multiple
  output devices. Currently supported output targets include
  the X Window System, win32, and image
  buffers. Experimental backends include OpenGL (through
  glitz), Quartz, XCB, PostScript and PDF file output.

Hi,
I've installed cairo and rcairo on Ubuntu and none of the examples in
the samples directory works but png.rb.
Launching ps.rb gives me an empty file test.ps with the following error
:

ruby: symbol lookup error: ../packages/cairo/ext/cairo.so: undefined
symbol: cairo_ps_surface_create_for_stream"

If you can help thanks, I'm new to Ruby.

It seems that this is a cairo library search problem. It
seems that your rcairo was compiled with cairo which
supports PS/PDF but you use rcairo with cairo which does not
support PS/PDF.

Thanks,
