webkit-gtk: Symbol not found: __cg_jpeg_resync_to_restart

[drs@…]

My os/architecture information is:

Darwin XX.local 12.3.0 Darwin Kernel Version 12.3.0: Sun Jan  6 22:37:10 PST 2013; root:xnu-2050.22.13~1/RELEASE_X86_64 x86_64

When attempting to upgrade via 'port upgrade outdated', I find that upgrading webkit-gtk to 2.0.3 fails with:

:info:build clang: warning: argument unused during compilation: '-pthread'
:info:build dyld: Symbol not found: __cg_jpeg_resync_to_restart
:info:build   Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
:info:build   Expected in: /opt/local/lib/libjpeg.9.dylib
:info:build  in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO

I find that reverting to "webkit-gtk @2.0.1_0+quartz+video" resolves the issue. No other changes were made to environment or macports state other than moving the Portfile for webkit-gtk back to the 2.0.1_0 version with the dependency updated to 'port:harfbuzz-icu'.

Note that neither DYLD_LIBRARY_PATH nor DYLD_FALLBACK_LIBRARY_PATH is present in my environment.

I will attach the build log and the modified Portfile.

MacPorts does not use your environment when it's running. It uses its own sanitized environment, controlled from macports.conf.

I can't think of a reason for this to be happening, other than the one you already ruled out.
