[Cairo] compiling on Slackware 9.0

[Roman Bednarek]

Hi.
  Has anyone compiled the library under slackware? I do not know much
about auto* tools, so I cannot find the couse of an error:
./configure: line 17894: syntax error near unexpected token `LIBPIXREGION,'
./configure: line 17894: `PKG_CHECK_MODULES(LIBPIXREGION, slim >= $SLIM_REQUIRED

  Maybe you can say what is missing? If not, could you describe more
precisily which tools and libraries are needed?
  Thanks for any help.
