configure has:

   $as_echo_n "checking PANGO_FT2_LIBS... " >&6; }
                PANGO_FT2_LIBS=`$PKG_CONFIG --libs "pangoft2 >= 1.38.0"`
                { $as_echo "$as_me:${as_lineno-$LINENO}: result: $PANGO_FT2_LIBS" 
>&5
   $as_echo "$PANGO_FT2_LIBS" >&6; }


pkg-config --libs "pangoft2 >= 1.38.0" gives

   -lpangoft2-1.0 -lpango-1.0 -lfontconfig -lfreetype

and pkg-config --cflags "pangoft2 >= 1.38.0" gives

   -I/usr/include/pango-1.0 -I/usr/include/fribidi -I/usr/include/harfbuzz 
-I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include 
-I/usr/include/pixman-1 -I/usr/include/libdrm -I/usr/include/libpng16 
-I/usr/include/uuid -I/usr/include/freetype2


Weird. Look at /usr/lib64/pkgconfig/pangoft2.pc:

   prefix=/usr
   libdir=${prefix}/lib64
   includedir=${prefix}/include

   Name: Pango FT2 and Pango Fc
   Description: Freetype 2.0 and fontconfig font support for Pango
   Version: 1.43.0
   Requires: pango, freetype2, fontconfig >=  2.11.91
   Requires.private: glib-2.0 >=  2.38.0, gobject-2.0 >=  2.38.0, fribidi >=  0.19.7, 
libthai >=  0.1.9, harfbuzz >=  1.4.2, xrender, xft >=  2.0.0, cairo >= 1.12.10
   Libs: -L${libdir} -lpangoft2-1.0

Is there a difference to the pangoft2.pc on your system?
