I am working on perl assignment which is first perl code in our

provide your expert consultansy it will be great help to me

I am trying to use DBI in my program (simple program), below is the piece
of code

#!/usr/bin/perl -w
#use lib '/tools/dev/perl_modules/DBI/1.48/DBI-1.48';

BEGIN {
push @INC,"/tools/dev/perl_modules/DBI/1.48/DBI-1.48";

I'd guess that you're refering to the directory you unpacked & built
the DBI in. Don't do that, it won't work.

After "perl Makefile.PL", "make", and "make test" you should "make install"
to install the appropriate files into the appropriate directories.

You can change where the files get put using either the INSTALL_BASE=...
or PREFIX=... arguments to "perl Makefile.PL", See "perldoc
ExtUtils::MakeMaker" for more information.


Can't we use PERL5LIB environment variable to specify non standard perl
modules directories for compiling DBI as we do while running our
program ?

Yes you can, but it appears that the above script is specifying the
location of the DBI source, not the installation directory. You only
need to specify PERL5LIB if you are installing in a non-standard place
using PREFIX or similar incantation when building and installing. If
you follow the standard ``perl Makefile.PL && make && make test &&
make install'', then there is no need to set PERL5LIB.
