Udi,

Interesting result:
# texindy biota-to-set-wq-standards.idx
texindy: not a symlink as required for TeX Live at /usr/bin/texindy line 414.

Here's that function, starting at line 409:
if ( $is_TL ) { # TeX Live

     if ( $is_w32 ) {
         $xindy = "$cmd_dir/xindy.pl";
     } else { # LINE 414 follows immediately:
         die "$cmd: not a symlink as required for TeX Live"  unless -l $0;
         # FIXME: What this good for? Ain't xindy not also
         # "$cmd_dir/xindy.pl" in a Unix TL installation? Why does
         # Peter use the directory of the last symlink, where it just
         # finds the symlink again that is then expanded by xindy.pl?
         $real_cmd = $0;
         $cmd_dir = dirname($real_cmd);
         # Follow symlinks, but remember last one
         my $lcmd_dir;
         while ( -l $real_cmd ) {
             $lcmd_dir = $cmd_dir;
             $real_cmd = readlink($real_cmd);
             $real_cmd = "$lcmd_dir/$real_cmd"  unless $real_cmd =~ m,^[\\/],; # relative link
             $cmd_dir = dirname($real_cmd);
         }
         $xindy = "$lcmd_dir/xindy";
     }
     # FIXME: That's a very ugly kludge to achieve that the VERSION
     # file is found in output_xindy_release(). The real solution is to
     # copy the code from xindy.pl that determines $modules_dir and
     # $lib_dir and use that code as well.
     $cmd_dir = Cwd::realpath("$cmd_dir/../../xindy/modules");
     die "Cannot locate xindy modules directory"  unless -f "$cmd_dir/../VERSION";
} else {
...

And I don't know perl.
