freetype/fontconfig/cairo/pango version problem? / fontconfig compilation problem?

[human]

doc/rrdbuild.pod is not very clear about these versions:

grep cairo doc/rrdbuild.pod 
There is a problem with F<cairo.pc> on opensolaris. It suggests that
xrender is required for compilation with cairo. This is not true and also
 perl -i~ -p -e 's/(Requires.*?)\s*xrender.*/$1/' /usr/lib/pkgconfig/cairo.pc 
 wget http://oss.oetiker.ch/rrdtool/pub/libs/cairo-1.6.4.tar.gz
 gunzip -c cairo-1.4.10.tar.gz   | tar xf -
 cd cairo-1.4.10

using freetype-2.3.5, fontconfig-2.4.2, cairo-1.6.4, pango-1.21.1: Result:cairo does not find fontconfig

cairo (version 1.6.4) will be compiled with the following surface backends:
  image:         yes (always builtin)
  Xlib:          no (disabled, use --enable-xlib to enable)
  Xlib Xrender:  no (requires --enable-xlib)
  Quartz:        no (CoreGraphics framework not found)
  Quartz-image:  no (disabled, use --enable-quartz-image to enable)
  XCB:           no (disabled, use --enable-xcb to enable)
  Win32:         no (disabled, use --enable-win32 to enable)
  OS2:           no (disabled, use --enable-os2 to enable)
  PostScript:    yes
  PDF:           yes
  SVG:           yes
  glitz:         no (disabled, use --enable-glitz to enable)
  BeOS:          no (disabled, use --enable-beos to enable)
  DirectFB:      no (disabled, use --enable-directfb to enable)

the following font backends:
  FreeType:      no (requires fontconfig)
  Win32:         no (disabled, use --enable-win32 to enable)
  Quartz:        no (CoreGraphics framework not found)

the following features:
  PNG functions: yes

and the following debug options:
  gcov support:  no
  test surfaces: no
  ps testing:    yes
  pdf testing:   no (requires poppler-glib >= 0.8.0)
  svg testing:   no (requires librsvg-2.0 >= 2.15.0)

But as FcFini? is documented in fontconfig, this could also be a fontconfig configuration/compilation/installation problem, and only rrdbuild.pod should be corrected regards

order of directories in PKG_CONFIG_PATH is important

as not being able to get rid of old freetype:

rpm -q freetype
freetype-2.1.4-7.el3

I use

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

which lets cairo 1.6.4 recognize freetype another

export LD_LIBRARY_PATH=/usr/local/lib

configure and make works!

... perhaps helpful for users with old systems ;-))
