PL/Vision: new version needed?

I have a new goal. To try to put PL/Vision at a new stage: an 10g and 11g version.

I try to install it in my 10.2 version and I got a compilation error.
For now here are the changes I made in the code

Compilation error:
comment line 50 and 51 of PLVEXEC package specification
-- no_such_table EXCEPTION;
-- PRAGMA EXCEPTION_INIT (no_such_table, -942);

Unnecessary code:
comment line 162 of PLVEXEC package body
-- ELSIF code_in = -942 THEN RAISE PLVexc.no_such_table;
comment line 350, 351 of PLVEXEC package body
-- logit BOOLEAN := FALSE;
-- showit BOOLEAN;
