How2 prevent perl's searching "std directories"?

[kj]

Is there a way to prevent perl from searching "standard" directories
when looking for library files? Is there a way to set (as opposed
to append to) @INC on the command line when invoking perl?

Thanks!

perl -e'BEGIN { @INC = "/my/inc" }'

If you need to do this when invoking a script, it'd probably be easier
to write a little lib:nly module

package lib:nly;

sub import {
@INC = @_;
}

1;

and use

perl -Mlib:nly=/my/inc,/my/other/inc script

rather than

perl -e'BEGIN { @INC = qw|/my/inc /my/other/inc| }' -e'do "script"'

Is there a way to prevent perl from searching "standard" directories
I neglectd to mention that I want to control the searchpath for
the perl debugger. I'm trying to debug a perl installation, but
the debugger is crashing on me because it is reading the previously
installed (and incompatible) site libraries.

Thanks,

perl -Mlib:nly=/my/inc,/my/other/inc script

I tried

~/build/perl-5.8.2$ ./perl -Mlib:nly=lib -d misctmp003
../perl: relocation error: /usr/lib/perl/5.8.2/auto/IO/IO.so: undefined symbol: Perl_Tstack_sp_ptr

....so perl is still looking at the standard directories.

OK, it worked. I needed to add -Ilib to the command line.

Cool! Thanks.

Look into the lib pragma. Usually you use it as

use lib '/path/to/lib';

in a program, or as

-Mlib=/path/to/lib

on the command line, but you can do

no lib '/path/to/remove';

as well. For the command line, insert a "-" right after the "M":

-M-lib=/path/to/remove,/another/path/to/remove
