only take place if the condition harfbuzz>=0.9.9 is met. If the fontconfig
test does not take place this will avoid the tests for freetype>=2.1.5 and
xft>=2.0.0 and cairo-ft>=1.7.6. The consequence is that if your system has
the correct fontconfig, freetype, xft and cairo-ft, but no harfbuzz,
configure will fail with a
configure: error: *** Could not enable any backends.
*** Must have at least one backend to build Pango.
Instead of a nicer: "harfbuzz>=0.9.9 requirement not met" (after verifying
that correct freetype, xft, cairo-ft and fontconfig are installed).
With regard to pango-1.34.0, I suppose the message intended (with the
dependence on a release candidate fontconfig) is that this pango version
should be avoided like the plague unless there is some specific new feature
or bug fix which you require to test.
