How do I keep my own module/library directory?

When you build modules, use the PREFIX option when generating Makefiles:

    perl Makefile.PL PREFIX=/u/mydir/perl

then either set the PERL5LIB environment variable before you run scripts that use the modules/libraries (see perlrun) or say

    use lib '/u/mydir/perl';

This is almost the same as

    BEGIN {
	unshift(@INC, '/u/mydir/perl');
    }

except that the lib module checks for machine-dependent subdirectories. See Perl's lib for more information.
