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.

I've installed cairo and rcairo on Ubuntu

Thanks!

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"

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,
