in thread module location

I thought you had it, but not I get this error: 
   Can't find DBI! at ./test.pl line 4.

Here is the absolute path to the DBI.pm file: 
   /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi/DBI.pm

[download]
and the @INC path shows this in 'perl -V': 
  @INC:
    /usr/lib/perl5/5.8.0/i386-linux-thread-multi
    /usr/lib/perl5/5.8.0
    /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi
    /usr/lib/perl5/site_perl/5.8.0
    /usr/lib/perl5/site_perl
    /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi
    /usr/lib/perl5/vendor_perl/5.8.0
    /usr/lib/perl5/vendor_perl
    /usr/lib/perl5/5.8.0/i386-linux-thread-multi

What am I missing? Thanks for your help!

    Well, there are a few solutions to this.

    My bug was: require DBI looks for "DBI.pm" because DBI is a bareword; but this does not work if you put the bareword in a variable and require that instead.

    One simple solution is to just:

    ./test.pl DBI.pm

    If you don't like that, you can change the eval to a string eval, which will interpolate the package name into a bareword before require sees it:

    #!/usr/bin/perl -w
use strict;
my $perl_module = shift;
eval "require $perl_module" or die "Can't find $perl_module!";

    This would be the more flexible solution, since it would handle things like ./test.pl DBD::PgSQL (assuming that makes sense... basically, any module with ::'s in it).
