Ah, good point - I hadn't noticed that!

Unfortunately it is not that easy:
: leinen@macsl[tmp]; DYLD_LIBRARY_PATH=/opt/X11/lib ./a.out
dyld: Library not loaded: /usr/local/opt/freetype/lib/libfreetype.6.dylib
Referenced from: /private/var/tmp/./a.out
Reason: Incompatible library version: a.out requires version 24.0.0 or
later, but libfreetype.6.dylib provides version 19.0.0
Abort trap: 6
...but if I recompile the test program with -L/opt/X11/lib, then it
crashes:
: leinen@macsl[tmp]; cc -g hb-ot-test.c -L/opt/X11/lib `pkg-config freetype2
harfbuzz --cflags --libs`
: leinen@macsl[tmp]; objdump -macho -dylibs-used /var/tmp/a.out
/var/tmp/a.out:
/opt/X11/lib/libfreetype.6.dylib (compatibility version 19.0.0, current
version 19.6.0)
/usr/local/opt/harfbuzz/lib/libharfbuzz.0.dylib (compatibility version
20504.0.0, current version 20504.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 1252.250.1)
: leinen@macsl[tmp]; ./a.out
HarfBuzz Version: 2.5.3
Segmentation fault: 11
So I guess all I have to do is make sure Emacs doesn't use the old
libfreetype in /opt/X11/lib, but rather the newer one in /usr/local/lib
(and hope that that one works in an X11 environment...)
I'll be in meetings for the next few hours, but will let you know what
happens once I find time to do the above.
Thanks a lot so far!!!
Cheers,
