[apaprocki]

Bug appears to be in GenLibDeps.pl:99

open UNDEFS,
"$nmPath -g -u $Directory/$lib | sed -e 's/^ *U //' | sort | uniq |";

It assumes that nm can be run with -g and -u simultaneously.

Usage: nm [-ACfhlprTv] [-B|-P] [-e|-g|-u] [-d|-o|-x|{-t [d|x|o]}]
[-X{32|64|32_64|d64|any}] [--] File ...

The nm usage shows they are exclusive:

   -g
        Displays only external (global) symbols.
   -u
        Displays only undefined symbols.

[apaprocki]

Changing the .pl script to run -g first and then duplicating the same block of code for the run with -u allowed it to proceed.
