Hi everyone,

As some of you may know I'm working on a new and improved script to find
missing library dependencies, which is much faster than the old
findLibDepends.sh and uses readelf to read the dynamic section instead
of relying on ldd which also lists second and higher level dependencies.

The script is not yet fully up to working order, I still need to handle
sorcery providers correctly and I still need to get my index updates
watertight, though using the script I have made a list of all missing
dependencies of the spells installed on one of the boxes I maintain. I
have put this list up on the wiki[0] so that we can start resolving
these missing dependencies, thus improving the quality of our dependency
tree which is currently lacking.

I would request everyone who has a bit of time to spare to look at the
list, pick one or more spells and resolve its missing dependencies. Of
course doing so requires checking whether the dependency is optional or
not and correctly adding the dependencies to the DEPENDS files. There
are bound to be some optional dependencies which cannot be configured
through a package's configure script or similar for which we would need
to file upstream bugs.

I hope working together we can all help to improve the quality of our
dependency tree, hopefully lowering the possibility of breakages
significantly.
