The 'coders' directory contains the modules, however often these als
need other external libraries for the implementation of that format.
TIFF for example not only needs the 'coder' module, but that module
needs the libtiff library.
For example
ldd /usr/lib/ImageMagick-6.5.7/modules-Q16/coders/tiff.so
...
libtiff.so.3 => /usr/lib/libtiff.so.3 (0x00e07000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x00447000)
...
shows that the coder for tiff also needs these two (and other)
libraries.
IM is does it in this way so that if a particular format is not used,
the coder and libraries involved do not need to be loaded or even exist.
This way IM still runs on systems that do not have all the libraries.
Also some specific format (and coders) also use external programs.
for example postscript and PDF handling needs ghostscript installed.
The two configuration directories are also needed. One is shareable or
system independent (text configuration) while the other are system
dependant binary configuration.
/usr/share/ImageMagick-6.5.7/config/
/usr/lib/ImageMagick-6.5.7/config/
