No. It's a problem that's been caused by the combination of the new
linker, the 10.4 version of ImageIO, the fact that you had already
built copies of libjpeg et al. on your system and the fact that
there is a symlink in the SDK.
IMO the symlink in the SDK is a mistake, so the best fix is
sudo rm /Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib
[...]
Besides that, I personally consider the addition of unmangeld variants
of libJpeg et al. without corresponding headers and an obvious way to
override an far mor annoying flaw.
In an Image manipulation app I typically have an high interest to
- open images using the API de jour like ImageIO
- Override flaws like e.g. not-supported TIFF tags and EXIF properties
with parts of libTIFF + libEXIF.
Maybe I'm missing some point, but I don't see why _I_ have to mangle
symbols or mess with two-level namespaces just to avoid conflicts with
an ImageIO implementation detail I cannot even use. To bad that
decision can not be reversed for backward compatibility sake, so
radar'ing is a plain waste of time.
