is there a list of lib dependencies?

  X Server modules are loaded dynamically, but there are also static
libraries to which the server is linked.

  Your best bet to quickly find definitions is to use something like ctags.
I think several editors support multiple projects/tags.
 If you just want to find where the symbol is defined, you can use a command
like:
for f in `list-of-shared-binaries`; do
  objdump -T $f | grep $symbol-name | grep -v '*UND*' && echo $f
done

  If you are building a module, you don't need to explicitly link to those
libraries, as the symbols end up being exported by the X Server. But you are
better using only symbols defined in the headers in /usr/include/xorg/*.h.

  Depending on what build system you use, you may also need it to somehow
accept creating shared binaries with unresolved symbols, if that is the
problem. I have a script that finds missings symbols, attached to a
freedesktop bugzilla (the script only checks for symbols that are
present in some Xorg modules and doesn't know if the module will be loaded
at runtime).
