	Very strange, the build I made comes with its own libnetpbm:

mrspc [/usr/local/lib] file libnetpbm.10.26.dylib
libnetpbm.10.26.dylib: Mach-O 64-bit dynamically linked shared library x86_64

	Of course, I don't have fink in my path at all. Now, I'm a bit
behind the curve and I use 10.5.4 on this mac. For the lib you mention, the ones
I use are:

mrspc [/usr/local/lib] file libpng.3.25.0.dylib libjpeg.62.0.0.dylib libpng12.0.25.0.dylib libtiff.3.dylib
libpng.3.25.0.dylib:   Mach-O 64-bit dynamically linked shared library x86_64
libjpeg.62.0.0.dylib:  Mach-O 64-bit dynamically linked shared library x86_64
libpng12.0.25.0.dylib: Mach-O 64-bit dynamically linked shared library x86_64
libtiff.3.dylib:       Mach-O 64-bit dynamically linked shared library x86_64

	Perhaps you have two sets of libs co-habitating?

> mv lib/libTIFF.dylib  lib/libTIFF.dylibo
> mv lib/libPng.dylib  lib/libPng.dylibo

	The capitalization here is quite suspect, this is the format used
by the native OSX version of those libs. Now, the mac native version of
those libs are only 32-bit... But with the case-preserving/case-insensitive
brain damaged HFS+, they can and will overwrite the libs I built.

	It'd be interesting to use DTrace to find out precisely which lib
gets open at runtime.
