If you run that through splain you'll get 
 Empty compile time value given to use lib at /proj/zn_ver_user2/sidsh
+a/build_plugin/infra/lib/BuildPlugin.pm line 32.
Use of uninitialized value in require at
        /proj/zn_ver_user2/sidsha/build_plugin/infra/lib/BuildPlugin.p
+m line 33 (#1)
    (W uninitialized) An undefined value was used as if it were alread
+y
    defined.  It was interpreted as a "" or a 0, but maybe it was a mi
+stake.
    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl will try to tell y
+ou
    the name of the variable (if any) that was undefined.  In some cas
+es
    it cannot do this, so it also tells you what operation you used th
+e
    undefined value in.  Note, however, that perl optimizes your progr
+am
    anid the operation displayed in the warning may not necessarily ap
+pear
    literally in your program.  For example, "that $foo" is usually
    optimized into "that " . $foo, and the warning will refer to the
    concatenation (.) operator, even though there is no . in
    your program.

I explain /demonstrate why its uninitialized in Re: ADD directory to @INC using a string variable (not when variables initialized use BEGIN)

But I really just wanted to respond to say eew at your 60-entries of @INC, because whatever your reasons, 60-deep-@inc is eew :)
