 Replying to [ticket:943 epatton]:

 > I have compiled Grass 6.5 from a fresh checkout from svn, set --with-
 cairo, --with-cairo-libs=/usr/lib, and --with-cairo-includes=/usr/include.

 You should never need to specify /usr/lib or /usr/include explicitly
 (however, recent versions of GCC will explicitly ignore them, so it's
 harmless).

 On Linux, you should only need --with-cairo, which obtains the compiling
 and linking flags via pkg-config. The --with-cairo-includes, --with-cairo-
 libs, and --with-cairo-ldflags switches are there for platforms lacking
 pkg-config.

 anything in a successful case, either.

 It prints whatever you specified for --with-cairo-ldflags. If you didn't
 use it, then it won't print anything.

 If the cairo driver gets built, there's nothing wrong with the configure
 switches. If it doesn't work, that suggests a bug in either the driver or
 the GUI.
