Two points to note:

1. IIRC 'lvu links' works by using ldd to find any linked-in or linked-to
   libraries, and therefore will only work with C/C++ like compiled code.
   I've seen that for Python or Perl modules for example, it doesn't work
   properly and gives a list of *all* modules that have installed libraries.

2. Some modules depend on features that could be supplied by one of several
   other modules, so what shows up on your system might not be the complete
   story. For example, for your recent 'jasper' submission, you added an
   optional_depends on %GLUT (i.e. either freeglut or glut) but freeglut
   conflicts with the mesa-lib that I have on my system with NVIDIA cards.
   Which begs the question of whether the %GLUT specification is complete.

Therefore adding any missing dependencies is not always straightforward.
