According to John Polstra:

Except that when I'm testing this, the program is not yet installed and
still belongs to me:
-rwxr-xr-x 1 roberto staff 51047 Jan 7 01:53 suidperl*
so it should respect LD_LIBRARY_PATH.

It is recorded in a wrong way IMHO
Shared object dependencies:
-llibperl.so.3.19 version 0.0
-lm version 2.0
-lc version 3.0
-lcrypt version 2.0
Even if it were recorded as libperl.so.3.19, it should be able to find it
with LD_LIBRARY_PATH no ?

It seems to work the same way with and without the ','.
