I found something.
When I checked out the Gnuplot.app that was shipped along with the
Octave-3.4.0 OS X app, I noted the following:
$ otool -L
/Volumes/gnuplot/Gnuplot.app//Contents/Resources/lib/libfreetype.6.dylib
/Volumes/gnuplot/Gnuplot.app//Contents/Resources/lib/libfreetype.6.dylib:
/tmp/gnuplot-i386/lib/libfreetype.6.dylib (compatibility version
13.0.0, current version 13.2.0)
$ grep -ir DYLD_LIBRARY_PATH /Volumes/gnuplot/Gnuplot.app/
/Volumes/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot:DYLD_LIBRARY_PATH="${ROOT}/lib:${DYLD_LIBRARY_PATH}"
/Volumes/gnuplot/Gnuplot.app/Contents/Resources/bin/gnuplot:
DYLD_LIBRARY_PATH="${DYLD_LIBRARY_PATH}" HOME="${HOME}"
GNUHELP="${GNUHELP}" \
I was able to reproduce your issue. There are two things going on here:
1) Your original assumption was correct, and mine was not: prior to
the 10.7.3 update, libfreetype.6.dylib had
$ otool -L /Volumes/FreeAgent\ GoFlex\
Drive/Backups.backupdb/Fiona/Latest/MacHD/usr/X11/lib/libfreetype.6.dylib
/Volumes/FreeAgent GoFlex
Drive/Backups.backupdb/Fiona/Latest/MacHD/usr/X11/lib/libfreetype.6.dylib:
/usr/X11/lib/libfreetype.6.dylib (compatibility version 13.0.0,
current version 13.2.0)
(Time Machine is so handy)
and now it has
$ otool -L /usr/X11/lib/libfreetype.6.dylib
/usr/X11/lib/libfreetype.6.dylib:
/usr/X11/lib/libfreetype.6.dylib (compatibility version 14.0.0,
current version 14.2.0)
2) However, that shouldn't have broken Gnuplot for you. Going from
an older to a newer compatibility version of a library is fine.
What broke it is the use of DYLD_LIBRARY_PATH internally.
DYLD_LIBRARY_PATH is *not* analogous to LD_LIBRARY_PATH in GNU/Linux,
and it overrides the whole library lookup path, as I mentioned before.
Here's your error again:
dyld: Library not loaded: /usr/X11/lib/libfreetype.6.dylib
Referenced from: /usr/X11/lib/libfontconfig.1.dylib
Reason: Incompatible library version: libfontconfig.1.dylib requires
version 14.0.0 or later, but libfreetype.6.dylib provides version
13.0.0
What happens is:
1) DYLD_LIBRARY_PATH is set to point to the libfreetype.6.dylib inside
of Gnuplot.app.
2) /usr/X11/lib/libfontconfig.1.dylib would normally try to link to
/usr/X11/lib/libfreetype.6.dylib, but since DYLD_LIBRARY_PATH is
pointing at Gnuplot.app/Contents/Resources/lib, it instead tries to
link to Gnuplot.app/Contents/Resources/lib/libfreetype.6.dylib.
3) Originally the libfreetype.6.dylib in /usr/X11/lib and
Gnuplot.app/Contents/Resource/lib were at the same version, so that
either one would satisfy libfontconfig.1.dylib.
4) However, after the 10.7.3 update, the libfreetype.6.dylib in
Gnuplot.app is now too old for what the new libfontconfig.1.dylib is
expecting, and so you get an error.
The error message is confusing because it says that
/usr/X11/lib/libfreetype.6.dylib wasn't loaded. It mentions this
particular library because that's what is encoded within
libfontconfig.1.dylib.
A workaround (it worked for me, anyway) is to replace all instances of
DYLD_LIBRARY_PATH with DYLD_FALLBACK_LIBRARY_PATH in
Gnuplot.app/Contents/Resources/bin/gnuplot.
DYLD_FALLBACK_LIBRARY_PATH doesn't override the library search path,
but rather provides a place to look if a library isn't found in the
normal paths. Its behavior is more like what GNU/Linux people expect
from LD_LIBRARY_PATH.
Anyway, try my workaround.
